Review: Stream desertcart Music HD in 24bit/192kHz resolution on your TV! - Most if not all TVs downgrade the audio to a much lower resolution. To get around this limitation DON'T connect the Cube to the ARC. For example, I'm connecting the cube to my TVs 3rd HDMI input instead of the ARC. My TVs ARC is connected to my Marantz M1 Amp which drives my speakers. That's it, the rest is just a matter of getting all the settings correct. In case you're wondering, the Cube still functions to control my TV and amp with its IR blaster! I control every function with my voice as if connected to the ARC AND desertcart Music is playing at 24bit/192khz (see picture) No more downgraded resolution.
Review: Messed up sound and display settings..update #4 - Update 11/12/25: So after having written the below review I decided I should give an update to the issues below. I've had other streaming devices since then and I have to admit that the fire tv cube beats them all. Reasons: The" best available" setting is actually the best setting. What it does is that ot converts DD+ sound to Multichannel pcm which is a lossless and uncompressed quality and passes it to the AVR. The AVR will show Multichannel 5.1 . It is the best sound you can get. I came to this conclusion after months of testing and research. Roku ultra has passthrough but it just passes the compressed format DD+ to the AVR so the AVR displays DD+. The TV turning off big is fixed. 10/4/23 update: Now another bug has appeared. When I watch on my LG C3 OLED TV the TV turns off automatically after a while. Sound continues but no picture. I initially thought it was my tv. Got another unit ,same TV, and the same issue happened. Then I decided to watch ony Roku ultra and have not had any problems so far. Tried the cube again 2 days ago and issue returned. I even turned off equipment control and reset the cube but didn't work. So now I'm not using it. It's just sitting there looking pretty. 7/23/23: Just to update that the video issue has been fixed. The audio issue not so. 11/23/22: Still no fix. Reverts to 1080p despite setting to Auto. Now noticing jitter or stutter on video when playing 4k content. Changed settings of Match frame rate to on but didn't resolve issue. Constantly checking display settings. Given up and using my other streaming device with no issues. Did not expect this from desertcart. 11/15/22: So since purchasing this there have been a number of updates installed but NONE have fixed the issue of sound and display settings as mentioned in my previous updates. This is truly disappointing and makes me want to use this device less often than I would like to. 11/9/22: Still issue with display resolution defaulting to 1080p. Always have to check before playing something. No fix. Not acceptable for a "high-end device" Update 10/29/22: Still no luck on best available sound settings outputting DD+. But now another issue. Whenever I awaken the cube the display resolution defaults to 1080p even though I set it to Auto(up to 4K). It's frustrating to have to change this every time I want to watch something. So many bugs! I've had many fire tv sticks over the years and also a 2nd Gen cube which I returned because it wouldn't play Dolby vision. Thought I'd give this a try since all the upgrades were compelling. Faster, built-in Ethernet port, HDMI in, supporting all sound and picture formats. So I set it up withy TCL tv and Sony receiver . Setup was a breeze. It recognized my TV and receiver. For some reason the picture quality in display settings was defaulted to 1080p. I changed it to upto 4K. Sound settings were "best available ". When I played content it would only play in PCM (stereo). I tried Dolby digital and Dolby Atmos content. Dolby Atmos would play as Atmos +PCM, not Atmos +DD+ as it should. I checked ally settings on the TV and receiver and all was good but couldn't get DD+. Called tech support and was told that it may be a software issue and may get fixed in a future update. Really??. All the hype about how this device is the fastest and best on picture and sound yet it can't output "best available" sound. I'm sure best available is not PCM. Tech told me to set the sound settings to Dolby digital plus. That corrected the issue but it was a let down. I'm hoping it doesn't revert back to PCM. Will see how it goes and update but so far disappointed. The super resolution setting really doesn't add much to enhance the picture quality of SD or even 720 or 1080p resolution. And that was one of the main features that enticed me to buy it. Update 7/2/23: The video resolution issue is now fixed but the audio issue still persists.

## Questions & Answers

**Q: Hi does the ethernet port speed support gb?**
A: No it does not.  The ethernet is 10/100 - does not support Gigabit speed.  I recently replaced a Roku Ultra which was having a great deal of trouble with 4k Ultra HD content due to the Ethernet port being only 10/100.  While a 4k stream should not require more than 100mbit on its own, my home network has almost 30 devices on it.  The Roku was one of the only media devices with 10/100.  When bandwidth is being apportioned from the router, it is not enough (due to overhead).  Replaced it with a Shield TV Pro and so far, everything is working.  If this unit had come with a Gigabit port, I would be ordering one right now.

**Q: Will this device allow me to watch OTA channels?**
A: It will not let you watch OTA channels natively, however you have a couple of options (without subscriptions to streaming).  First, if you can get your hands on the Fire TV recast (Discontinued by Amazon) it'll connect with little effort.  Second, and better is by buying a Tablo DVR.  There are a couple of options from them. Some of their OTA DVRs have an HDMI output you can connect and watch through the Cubes HDMI input or a network DVR, like this one that works fine with all Fire TV devices  https://www.amazon.com/Tablo-Quad-OTA-Cord-Cutters/dp/B07PLVF8B7/ref=mp_s_a_1_4?crid=1P9BZHEYMGA6T&keywords=tablo&qid=1669584572&sprefix=tablo%2Caps%2C99&sr=8-4&ufe=app_do%3Aamzn1.fos.08f69ac3-fd3d-4b88-bca2-8997e41410bb

**Q: Will it support a Plex Server?**
A: It could probably run a plex server. But Plex would have to create server software specifically for it. Or you would have to find someone who has side loaded it to show you how.  Plex Server and Plex Client are two different things.

I use an Intel NUC with an Intel i5 processor using USB 3.0 External HDDs for files. Its been great for low power always on Plex server. Assuming you are looking for a low power option. It idles at 5W and underload uses at most 25W.

**Q: What's a compatible usb storage adapter and maximum memory to buy?**
A: I am using the "Anker 2-in-1 USB 3.0 SD Card Reader", Model 68ANREADER-B2A with a 128gb SD card, but I do not know the max size. They do support NTFS which should support lager sizes, but I have not seen anything in the user guide. Previous cubes maxed out at 128k!

It also appears it will not recognize 2 sd cards simultaneously!

### ⭐⭐⭐⭐⭐ Voice recognition works great now!
*by M***N on November 3, 2022*

I just bought this product. Easy to install and the picture quality is wonderful. However, I can't get the sound to work for Alexa, the cube doesn't respond to any commands and doesn't talk to you. Both my LG TV and this version of the new Fire Box are brand new. It may be my issue and I haven't figured it out yet. Moving into a new home is hard enough, then to try and find time for the items you purchased to make your home amazing takes time. I started ordering last year since it took a year for this house to be built. I won't order things a year in advance anymore. New versions have come out and they are the same price or a little more. I'd rather have the latest version. I have other Alexa devices at home, so I am not worried about that part not working. The remote is great and easy to use, and I normally don't ask my TV to turn the channel...lol. I used to use foil on the antenna so I could get a fuzzy picture or a coat hanger so my brother and I could watch Batman as kids. It will get a higher rating if I figure this sound issue out. However, right now it is worth the price just for the picture quality. WOW, an Amazon Rep. phoned me and fixed my issue. She was wonderful and fixed the issue which was my own fault. It took about 5 minutes, and it was talking up a storm. Update: This cube has caused a lot of issues. I gave my old cube away to my sister, so I am SOL. This cube got so hot on so many occasions that it burned the top of my dresser. It freezes and will not work. It doesn't connect to my new Echo or old Echo devices. Tech support told me that it was because "I didn't buy them together!" So, I now use my Yamaha soundbar. I don't even like to call foreigners anymore. Please bring back the English-speaking techs and operators, it is so frustrating that I hang up and just deal with the fact I bought an expensive POS. I even wrote to Amazon and nothing, left my phone number, and asked for a return call. I bought a bunch of Echos for this new house and haven't even taken them out of the box. Nothing is pairing with the TV, Echo shows, or Echos. They do not support each other. I also have the Eero 6 Pro system in my house and the new Echo won't even connect to that. I'm terribly upset and the resolutions the tech team talks about are ridiculous.
