Try change in #258 at first. I don't know any hardware details, so if you cannot get things to work with the native (direct) ALSA tools like amixer/alsamixer/aplay/arecord, then you...

From the first look this is very unclean update. Some modifications are straight, but the big ones seems a bit step back. Some comments: Header to Header1 is not finished...

I'm sorry but you're mixing PCM device initialization with mixer control. The Switch/Volume control should be in Value section - `CaptureMixerElem`. See other configurations for an example. For your case,...

Notes for me. HDA driver creates only Master volume controls for this hw: ``` Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback...

Could you attach `alsaucm -c hw:0 dump text` output? Replace 0 with the HDA card number (`aplay -l`).

I don't see an obvious error here. Could you attach the pulseaudio debug log? https://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems

The wrong comment in the PA config broke everything (duplicate whole line and comment out the `use_ucm=0` version): ```Failed to load module "module-udev-detect" (argument: "#use_ucm=0"): initialization failed.```

If you select the 'Speaker' device, then there is no sound ? Could you attach output from `amixer -c Generic_1 contents` command when the playback using the UCM device is...

UCM describes the hardware in a different way than the legacy PA probe, thus there are some differences. I am aware about it (missing multichannel configs). On the other hand,...
