HDMI Audio Extractor 4K HDMI to Optical Audio Adapter Converter Video Splitter Supports HDCP DTS 5.1 PCM Compatible for PS4 Fire Stick Blu Ray Player(Not Support ARC)

My only option for decent audio on a HP Pavilion Envy with a nVidia 3070ti was using its HDMI Audio. USB audio options would lock up Win11 do to a USB power issue with the MB, there is no expansion for internal Sound Cards and the onboard is extraordinary pathetic for a gaming PC. Win11 kept messing up the settings with a Denon X2800H AVR and blocking a straight nVidia HDMI Denon ARC to HDMI Monitor connection at random. So I tried this Musou 1080P HDMI Audio Extractor to Optical Toslink(SPDIF) and it is working so far with no hiccups or glitches. The Denon saw the Optical Toslink(SPDIF) audio connection right away and sound is working very cleanly. Win11 recognizes I am connected from nVidia HDMI to a MS-HDMI-RX device. Win11 doesn't recognize a Optical Toslink(SPDIF) connection as the nVidia HDMI is the primary connection and the Denon is just a passthrough. This explains why it won't see a 5.1 connection on the Denon as HDMI is 2 channels, not 5. Nevertheless, a very inexpensive workaround for my PC rig that works fine. The Denon put the soundstage in Matrix Mode with headphones plugged in which is a ProLogic mode that turns out very good clarity and sound for voice & music. I know there are many different reason people use this converter with hit n miss. It was a home run hit for me

This item is perfect for my needs. I have a projector that has 1 HDMI input and a small speaker. I mounted my projector, so I bought an HDMI splitter as well. If you see the photos. I connected the projector HDMI to the Output and I connected the HDMI splitter to the Input of this device. Also, since I wanted a better sound, I connected the optical cable from the device to my surround system and now I have great sound! You will need to provide power to this device via micro USB port. (Only USB cable included). If for some reason your display is acting up, just unplug the USB power cable and plug it back in. It should fix the issue of the display. The size is great and great value. It works as I intended to use is and the installation is self explainatory. (HDMI splitter is something I bought separate, since it prevents me from unplugging HDMI cables from my projector)

I use a computer monitor that doesn't have speakers to play my Nintendo Switch. I was plugging my speakers into the top of the Switch everytime I went from handheld to TV mode, which was just obnoxious. This was a simple device that solved that problem, now all I have to do is dock my switch and everything is already connected. No extra ports that I don't need and take up more space.

It works great, (so far) though, I did just get it today. So I can't speak for it's durability. I will update If anything changes. I didn't read any directions. It was pretty simple. HDMI cord to the converter and to my PS4. Another hdmi cable to the tv and the other side of the converter. Plug in the power supply and optical cable. Flip the switch on the proper setting. Bam. Good to go! Edit: I have had maybe a little over 2 months and it just burnt up. Smoke pouring out of it and my house is stinking. I unplugged this thing every time I was done with it, and haven’t used it much this month due to working all the time. so it’s not like it was on all day. Edit 2: I had this thing running to my PS4 (HDMI 3) and Blu-ray for surround (HDMI 2) now both those ports are fried and won’t get signal. Coincidence that it happened when this thing popped on me? I think not. Now I have to buy a new TV!

This device worked well for me. When attached to a Windows 11 PC, the list of PCM and surround sound modes it can handle are in the screenshots here. It can do up to 24-bit ,192KHz PCM, for those who are into "HiRes" digital audio. I was also able to use it to extract 24-bit, 192KHz PCM from the HDMI stream from a latest-gen. 4K Fire TV "Max" Stick, when playing "Ultra HD" music in the Amazon Music Unlimited app. Keep in mind, though, that DAC quality matters, and the DAC in this device, a "344C", which seems to be a VERY inexpensive clone of the Cirrus Logic CS4344, is likely not going to produce top-quality analog audio out of the 3.5mm stereo line-out jack on this extractor. I have not yet done any "critical listening" tests with the onboard DAC, but may do so, with the aid of a "Pure Class A" headphone amplifier, driving modded Sony MDR 7506 over-the-ear studio headphones. If you use a high-quality outboard DAC, fed by the optical Toslink output of this extractor, results should be better, to a (highly debatable) degree... The main chip is a GSV2001. This is a "1 In to 2 Out HDMI2.0 Repeater with Audio Extraction/Insertion", and extracts the 12S digital audio stream from the HDMI stream, and sends it to the onboard DAC, and also converts it to a S/PDIF bitstream for the Toslink optical output. The US32VF030A5 is: "is a microcontroller with an embedded 32-bit RISC-V core and ultra-low power consumption, low pin count and wide voltage operating range (3.0V~5.0V). It can run at up to 96MHz, has built-in 160K bytes of embedded Flash, 28K bytes of SRAM, and integrates ADC, RTC, multiple UARTs, SPI, I2C, PWM, IIS and other high-end peripheral interfaces. It has the characteristics of high integration, high anti-interference and high reliability."

The converter box itself works great, but the cords that came with it are bad. Initially I thought the box was busted as the video and audio kept cutting out every 5 to 10 seconds. After testing on multiple ports and getting the same issue, I finally tried a different HDMI cord I was using on another device and everything worked fine. The audio cord that came with it also has a bad bend in the red connector. Luckily I don't plan on using that cord. At least the USB power cord for it is working I guess? 1 out of 3 working cords isn't a good ratio though. Once up and running the converter works as intended. Just a bit disappointing I have to go buy another HDMI cable since I can't keep using the good one from the other device.

It just stopped working in less than a month

Perfectly working as expected getting dolby audio (5.1) through spdif , I have connected it to raspberry pi 3 and I am getting dolby audio through audio pass through option in audio settings, i have installed LibreELEC kodi on raspberry pi 3 and now I am getting dolby audio 5.1ch through spdif I am having Zebronics soundbar 5.1ch loved this hdmi extractor go for it I also checked with laptop getting dolby audio 5.1 but not through youtube only dolby audio movies available in laptop or connected pendrive but I don't like the quality of power adaptor looks very cheap and light in weight otherwise everything is fine. But I don't how much long this product will work because adapter quality is not good

Does not work No signal from RCA coming out. No signal from optical output coming out Went through all possible settings on Samsung TV

No optical cable, no hdmi cable...

not working. waste of money
