Hello list, https://bugtrack.alsa-project.org/alsa-bug seems to be down, so I'll try my luck here. Sorry if this was reported before. Something seemingly random powers down the internal speakers on my ThinkPad, sometimes after hours, sometimes after minutes. Headphones always work and the system beep is still played through the speakers if no headphones are connected. I tried to add various options for the snd-hda-intel module but nothing fixes this. After a few hours of tinkering I took a diff of the output of alsa-info.sh after a fresh reload of the driver and immediately after the speakers were turned off. The only difference is in the power state of this node. The power setting and actual change from D0 to D3. Node 0x1f [Pin Complex] wcaps 0x400501: Stereo Pincap 0x00000010: OUT Pin Default 0x901701f0: [Fixed] Speaker at Int N/A Conn = Analog, Color = Unknown DefAssociation = 0xf, Sequence = 0x0 Misc = NO_PRESENCE Pin-ctls: 0x40: OUT Power states: D0 D1 D2 D3 D3cold Power: setting=D0, actual=D0 I can temporarily fix the problem with hda-verb /dev/snd/hwC0D0 0x1f SET_POWER_STATE 0 instead of reloading the module, but I would much rather prefer a permanent solution. As I don't know the habits of this list for attaching logs and debug information, I'll try to keep it short. If you need more information, just let me know.
