The reboot is not necessary. For pipewire, the command `systemctl --user restart wireplumber` is sufficient to reload the new UCM configuration. I would start from scratch: 1) disable pipewire (`systemctl...

All amixer command should have `-c 1` argument otherwise the sound server (not hardware) mixer controls are printed. Have you tested all PCM devices directly (e.g. `aplay -D plughw:1,1 `...

If things does not work with the native ALSA API (ALSA drivers) then we cannot do much in UCM. I already provided the [debug information](https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/DEBUG.md) for UCM. The silent input...

This bug is stale. Re-open when required.

@liayn : Describe what does work with the current UCM. Also use native ALSA tools to access the USB driver directly, if you can use the target functionality. UCM is...

Could you show `amixer -c 4 info`, too ? Also, `alsaucm` tool may be in a different package than `alsa-utils` (e.g. `alsa-ucm-utils` in Fedora). If `alsaucm` test does not work,...

Try the above patch (4b8c56ceab4a7a32c2b07328876426f904233c49). It's just a variation of patch proposed in this issue description. I would expect, that more ALC4080 hw variants may not have the S/PDIF device...

The alsaucm dump provides all information for the current configuration to test the devices / jack names with the native ALSA tools. If you discover that something is set wrongly...

The debugging using the standard ALSA tools is described in https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/DEBUG.md . In the UCM dump, you see a list of used ALSA PCM device names and controls. If something...

If you remove (comment out) two last added lines (buffer_time, period_time) in fb69d0f0274b03e1ead0a7feeaceac608760dc72 , do things work better ?
