I have a notebook, where speakers suddenly stopped working. I use Debian testing (Stretch). Although speakers don't work, headphones work fine. It is not a hardware problem because they work If I boot into some other distro I have. Debian uses PulseAudio, but if I disable PulseAudio, the problem persists. So I guess the problem is in ALSA underneath, and it must be something muted or sound not routed properly. I'm testing with aplay, like this: $ pasuspender -- aplay -D hw:1 file.wav No errors given. Just no sound through speakers. I can hear the sound if I plug headphones. Looking at mixers (amixer and alsamixer), I can't find anything muted. I have attached amixer output as a text file. Can anyone help me debug this? -- Bruno Schneider
