Attach output from `alsa-info.sh --no-upload`. Also, try to determine the capture channel assignment - consult ucm source file https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/USB-Audio/Focusrite/Scarlett-18i20.conf .

@geoffreybennett : My opinion is that we should offer something working out-of-box without any extended tools. Then advanced users can switch to something else on demand. If you have information,...

@geoffreybennett is not right. We can detect the firmware using raw USB descriptors, because the supported channel count is a part of the USB descriptors. Please, provide raw USB descriptor...

The gain settings (which i2c_mangle sets) is in config file: ``` # # STV6210 baseband amplifier gain (0dB .. 16dB - 2dB step) # STV6210_BAMP="16dB" #DEMUXTS_OLD="yes" ``` The 16dB may...

There is work in progress: #499 . @amadeuszslawinski-intel Intel SST drivers were removed too early IMHO.

Could you show output from `alsaucm -c hw:sofhdadsp dump text`. The headphone device should be always defined in UCM.

I don't see UCM issue, there is `Headphone Jack` control: ``` control.8 { iface CARD name 'Headphone Jack' value true comment { access read type BOOLEAN count 1 } }...

@jerstlouis : Unfortunately, we do not add legacy configuration for new ASoC drivers to alsa-lib, because users have also other requirements (see bellow). So your special configuration is really an...

If you write 8000 frames and rate is 8000Hz then it's exactly one second. If you want to write frames to the remaining space (buffer), then use `snd_pcm_avail()`/`snd_pcm_avail_update()` to identify...

You can dump UCM mapping using `alsaucm -c hw:Audio dump text`. It's necessary to check 'Jack' and PCM device name assignents. Also, if the volume can be affected using any...
