Created attachment 257829 [details] Output of alsa-info Front panel mic works badly, optical output works. I haven't tested analog output. The mic boost is the only control that works for the mic gain, which results in noisy recording. There is lots of ultrasonic noise. Alsa-info attached.
Rear mic input does not work.
Another problem is that audio can play at the wrong samplerate. It's a weird test case but I have a 352KHz file that is playing at 192KHz for some reason: $ cat /proc/asound/card1/pcm0p/sub0/* access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 2 rate: 192000 (192000/1) period_size: 1200 buffer_size: 4800 card: 1 device: 0 subdevice: 0 stream: PLAYBACK id: ALC1220 Analog name: ALC1220 Analog subname: subdevice #0 class: 0 subclass: 0 subdevices_count: 1 subdevices_avail: 0 64 32768 state: RUNNING owner_pid : 6424 trigger_time: 11743.242554902 tstamp : 0.000000000 delay : 3208 avail : 1592 avail_max : 2552 ----- hw_ptr : 33203192 appl_ptr : 33206400 tstamp_mode: NONE period_step: 1 avail_min: 1200 start_threshold: 1 stop_threshold: 4800 silence_threshold: 0 silence_size: 0 boundary: 5404319552844595200
I suspect there is a configuration bug but deleting .asoundrc doesn't help. Is there no longer any way to purge ALSA? $ aplay /media/keantoken/old-home/keantoken/Music/Sound_Test/2L/2L-071_stereo-DXD_01_01.wav ALSA lib pcm_dmix.c:1052:(snd_pcm_dmix_open) unable to open slave aplay: main:788: audio open error: No such file or directory
