I have a Thinkpad T410 on which I run Arch Linux. I'm using pulseaudio as well. Sound seems to work properly: pulse starts, it seems to recognize and play nice with alsa, I can the proper stuff happening in the 'Playback' tab on pavucontrol when playing audio, etc. I even get sound out of my speakers. But, eventually, inexplicably, my speakers stop producing sound. Everything else seems to keep right on keeping on. I have not been able to determine what triggers this, so I cannot easily reproduce the issue. Here is what I knowRestarting brings sound backThe loss of sound appears to be time-based. I would say within an hour of playing a stream I lose soundThe sound only goes away when there is an audio stream playing: if I reboot and leave the computer alone for a week and then play a stream, I get audioPulse does appear to still be operating. I can plug in my headphones and listen to the audio streams, and I can also connect an external DAC and play audio through thatI'm at a loss as to what further debugging steps to take. What can I do to track down what is causing this issue and fix it?
Why do my laptop speakers stop working?
