Hello guys, and thank you a lot for being an awesome community.
I have recently installed EOS on a Minisforum HX90.
I could not verify through the minisforum forum page if it actually support digital output (SPDIF), but luckily EOS identified the SPDIF output.
The only problem is that I am not getting any output.
To put it in context, I also an old iMac (from 2011) which has combined stereo/SPDIF output from 3.5mm jack.
On that machine, which runs Manjaro, I can connect my soundbar using mini-toslink adapter, and everything works fine.
Sadly on the HX90 I get no digital output from the 3.5mm jack when I plug the mini-toslink adapter, yet the system can identify it.
Below I am showing the output from inxi -A (might update the post with more information later).
I am not sure @salvocos. From the information you posted I was able to find the information I shared with you, but as for what to do with it I am unsure. Hopefully someone more knowledgeable will be able to help you resolve this.
Hello @vazicebon and thank you for checking.
I am sorry if I did not write it in the main post, but basically I can get stereo output (e.g. heardphones) when I select Unitek Y-247A.
The problem is related to the Digital Output (SPDIF).
When I selected SPDIF I would still get stereo output, and I get not sound when I connect my soundbar (which requires a digital source) using the mini-toslink adapter.
Regarding the mixer, I have not touched anything, I am using a fresh installation.
TLDR: normal stereo output works, SPDIF is not working.
I use a HDMI TV for my monitor, and the TV has a SPDIF out fiber connector.
I just run a SPDIF cable over to the Yamaha A / V receiver and turn down the volume on the TV.
The A / V receiver has a 5.2 setup and leaving just a little audio coming out the TV actually adds a little depth to the music.
This is how I get decent audio from my ARM devices as most ARM devices are not equipped with SPDIF connectors.
Not familiar with SPDIF out connectors on most computer monitors, but if available it could be an alternative.
Like @adjagu previously suggested, I also think the problem might be related to the AMD ACP/ACP3X/ACP6x Audio Coprocessor drive not being loaded/installed.
If the next LTS kernel (6.1?) does not solve the problem, I am considering buying a cheap USB card with optical output. StarTech 7.1 seem to be an option for now.
You said you have a mac and a hx something. So it’s 2 device. Start by making sure the spdif do work on both. Just boot a live xubuntu , open terminal and : alsamixer , turn spdif to on / unmute. and play test signal or just a wave file. no 5.1 other strange file. if optical is supported, then in arch it will too. But getting it may be an issues sometimes.
