Wiistar HDMI Audio Extractor teardown (WS-E11B)

Back in 2020 I moved to a Roku Premiere as my primary streaming device. As my audio gear is older (pre-HDMI) I required something to split out the audio from the HDMI signal and the Wiistar HDMI Audio Extractor was a good fit.

At the time I mentioned that the device was a little suspicious, but it worked and kept working just fine for some time. After a year of trouble free operation, I did have a couple of times when the box would give up and pulling the power and rebooting it seemed to fix things. Stuff happens, no problem.

More recently it’s been acting up a lot. Blanking out, then coming back or not. Tapping or banging on the case seems to help ‘fix’ things temporarily. It appears that there is something not quite right with the power connection. This meant it was time to take things apart!

There is a horizontal seam on both sides of the device, you can see it right by the mini-USB connection and the switch. By pressing with a knife blade on this seam, I was able to un-snap the sides. This took a little doing, but was pretty easy. Some gentle wiggling freed the circuit board from the snap case.

No surprises here. It’s a single chip solution, likely decode HDMI, re-encode HDMI. There is likely a small audio amplifier circuit here to feed the 3.5mm jack. It’s pretty amazing that you can get something like this for the price.

The USB-mini power jack seems to be well affixed to the circuit board (no bad joints). I inspected the cable as well, and it looks to be a power only cable – only two pins on the plug. I tried adjusting the connector fit a little which might help my power problem (and I could have done from the outside of the case).

Then I took a closer look at that one chip..

Yup, that’s a blank, unbranded chip. I’m guessing this is a chip that failed QC and was discarded or sold off as seconds. Bunnie wrote about counterfeit chips which will give you an idea of how this chip may have ended up being used. In this case, they aren’t even trying to fake the chip – they just are trying to use one that was cheaper.

Well – it was interesting to open it up which turned out to be easy. I may have improved the power connection, but first try and it’s not working. Meanwhile I’ve ordered an AmazonBasics HDMI audio extractor as a replacement. The AmazonBasics device has a lot of (mostly) positive reviews. There is a youtube video teardown which while it’s terrible, does give a peek inside. There seems to be QC stickers on the circuit board, and the underside of the case appears to have FCC logos etc.

It’s likely a very similar solution, also needing a 5V 1A power supply. The pictures show you powering it from a laptop USB port, which is only going to provide 500mA – so there is some suspicious stuff going on here too with the marketing. Also, I suspect based on the comments it accepts up to 4k input, but can only output 1080p – which is fine for my needs.

Roku Premiere Review

Last year leading up to ‘Black Friday‘ we started to think about getting a modern console gaming system – our Nintendo Wii and PS3 were starting to feel a little dated both having been initially released in late 2006.

The Ps3 has been my blu-ray player, and streaming box at the heart of my home theatre. When I bought it, it was one of the best players you could get, and it was reasonably priced for the quality. I was frustrated earlier this year when the Plex app stopped working with the PS3 and it was clear that it would no longer be supported. We’d also noticed that Netflix was starting to feel like it took a long time to start up. The Amazon Prime app would also glitch out on the rare occasion.

We decided to get a Nintendo Switch, but that got me thinking about getting a new TV for the playroom so I could reclaim the theatre as my domain and have the after school game sessions happen somewhere else. This meant finally saying goodbye to the 24″ Sony Trinitron, it was still going strong 15yrs after we bought it.

The TV I picked was the TCL 55″ 4K Roku 55S423CA from CostCo. This is the 4-Series version of the set, but at the sub $400 price point it’s hard to go wrong. This is a 4k display: 3840 x 2160 = 8294400 pixels. If my math is right, that’s 20k pixels per dollar!

While I was looking forward to a modern TV, I had not really thought much about the ‘Smart TV’ features. I just wanted all those pixels. The TCL comes with Roku built in.

 

Yup, before I can even use the new TV I have to do a firmware upgrade and log into Roku, which also requires me to create an account. I’d much rather turn on my new toy and immediately get to use it, but it was a pretty smooth experience given it happened all over WiFi. You did need a second device to complete the setup (web browser), but at this point that’s not a bad assumption.

Once we get past the initial setup, the Roku TV experience is pretty slick overall. Netflix and Prime both appear to start faster than the PS3. While I initially purchased the TV primarily to be a game console display, it’s ended up being used to watch shows quite a bit. There is a fireplace in that room, as well as the treadmill where I often run and watch a movie.

Roku has a useful Android app, and that app supports local listening. This feature lets you redirect audio from the Roku to your android device (phone). Paired with a wireless bluetooth headset and I’ve got private listening.

With the PS3 starting to show its age, and the Roku feeling like a slick media player I began to think I should pick one up for the theatre. My requirements for such a device were:

  1. IR control – to integrate into the existing single remote setup
  2. SPDIF (optical or coaxial) output to feed the sound system
  3. Ideally wired networking

This make me think the Roku Ultra was the right choice, but frustratingly the Canadian devices are a subset of what was available in the US. I did think seriously about picking up the Ultra anyways, but concerns about getting an old stock (7th generation vs 8th),  software compatibility (Canada vs. US) and generally the hassle of actually buying one resulted in my picking the Roku Premiere.

The Premiere is an 8th generation device, is officially available in Canada, and is a really nice price point too. It only has one of the 3 requirements, but the Ultra only had 2. I did have a minor concern about the WiFi support not being dual band, but it turns out that hasn’t been a problem at all. I did find the wikipedia article helpful in finally arriving at a decision on which model to get.

If I can live without wired networking, I still need to get SPDIF output. This was easy to achieve with an add on HDMI box that stripped out the audio. The box I got is pictured in the top photo on the right. What is amusing is the back of the box.

This is very clearly a single box used to packaged multiple devices, and it suffers from some inaccuracies (no power supply required?). If I had to guess, the device I got was the HDV-M612. On Amazon it was advertised as “HDMI Audio Extractor HDMI to SPDIF/Toslink Coaxial 3.5mm Stereo Audio Splitter Converter with USB Interface for DVD HDTV STB Laptop PS4” – yeah, jam in all those keywords.

Aside from the suspicious packaging, the device itself was simple to setup. HDMI input, USB power, HDMI output, Coaxial SPDIF output. It has a small red LED indicating it’s powered, and it just works.

Maybe not surprising, but I thought it was pretty amazing that it was only 25hrs between ordering it on Amazon and having the two devices in my hands – with free shipping.

All in all, it was easy to setup and just works. The Roku experience is simpler than the PS3 and just works. It’s hard to argue with the quality and performance of the Premiere.

 

Home Theatre Seating – Octane Contour HR (Review)

It’s been a while (apparently 7.5 years) since I’ve written something about home theater here. To be honest, not a lot has changed in my setup. I’ve moved from having satellite TV and watching (buying) lots of DVDs to primarily streaming content – Netflix or Amazon Prime. We still enjoy the occasional Blu-ray, but the quality of streaming is good enough and the convenience factor is high. I think there is also a social aspect to keeping up with what your friends are watching as well.

There are many many options out there for seating. We’ve had two rows of couches from the start, but while couches are comfortable if you want to stretch out you either end up with some sort of foot stool – or you’re lying sideways. Honestly couches are a great solution, but they don’t have that fancy feel to them. Recliners are fancy. Many (all?) of the movie theaters today in our area have fairly nice recliners now.

This got us looking at recliners. Ideally we’d go for Canadian made, but after searching around buying local drives the price up to double or more (and the quality). The couch we had in the front row was really showing it’s age and needed replacing. Specifications I was looking for: leather with power reclining, Jenn also wanted to make sure they looked ok because quite honestly many options are fairly ugly.

With leather there is a lot of variation. You want to avoid any of the gel or bonded leather, these tend to be in the very low end of the market and simply won’t last or feel all that great long term. Sadly, leather appears to be completely unregulated and ‘top grain’ leather has a huge range as well. The other gotcha here is that the selection is nearly 100% online (at least in the price range we were looking at).

This is what we ended up getting:

BestBuy had a fairly good sale on, and they seemed to have real leather. When you go digging there are not very many reviews of these, and the result vary quite a bit. You can find Octane Seating – the company that makes these (in China). If you dig around, you find out that Octane allows for orders with custom fabric, and they have quite a range of grades they support as well. I think this explains why there is such a variety of reviews for products that are described similarly.

I think we bought a day before the sale ended. While I was waiting for the delivery, I couldn’t help but check the website – and I wasn’t very surprised to see this.

Ok, so the 3 day sale didn’t really end after 3 days, it was extended. Maybe they are trying to drain stock or something.

Yeah, at this point it’s starting to get a little bit silly. It’s the sale that goes on forever. I was wrong, on the 17th it returned to normal full price.

But… other models were now on sale. It seems there is always a sale for entertainment furniture, in fact – while I was writing the post they were back on sale for the same discount.

We’ve had them a few weeks and have really enjoyed them. Going for the power recliner was absolutely the right choice, it was worth the price increase for that. The Octane Contour HR have motorized headrests which I would recommend, as a feature it seems like a gimmick, but it is really useful (and comfortable).

The leather is not as nice as the love seat we bought a couple of years ago for basically twice the price. That said, the product that we received felt like it was worth the sale price. I wouldn’t pay the full price for these, or at least not what BestBuy is asking as full price. While these exact chairs may not be on sale, there seems to always be some of the models on sale. I’d also consider CostCo as another source.

The motors are audible, but quiet enough that it’s not too intrusive if you adjust while watching. I’m basically 6′ tall, and I fit but I suspect a taller person may not be as comfortable.

Oddities. The two seat pair, ships in 4 parts. Both back rests come off (and are easy for 2 people to put back on). You get 1 full chair (two arms) and 1 with a single arm. You simply place them together on the floor – and the weight keeps them in place. I expecting there to be some sort of locking / connection mechanism but no, it’s just placement.

Overall very happy with the purchase, already thinking about converting the 2nd row of seating to recliners too.

Pros:

  • Power recline and power headrest
  • Much more comfortable than the worn out couch they replaced
  • Fancy looking, premium seating at home

Cons:

  • Seats are not physically attached
  • Kids play with the controls
  • Leather quality is ‘ok’ and may vary from vendor to vendor

Footnote: We initially tried to buy a set of seats that EastPorters carries, but was sold / shipped by Staples. The ordering process seemed to go off the rails, so a week later we assumed they had just cancelled the order. Weeks later, a shipping company calls to arrange drop off of our assumed cancelled order. They ended up leaving seats on the front step with no signature. They did come get the unwanted delivery and we eventually got a 100% refund, but only after chasing them a bit. I wouldn’t recommend Staples for this type of purchase
