If the volume is still too low, run alsamixer again: resetting the codecs may have caused new sliders to become enabled and some of them may be set to a low value. $ wget -O hda-analyzer.py a=blob_plain f=hda-analyzer/run.pyĬlose the analyzer, and when prompted as to whether you want to reset the codecs, say "yes". If all the sliders are maxed out, and the volume is still too low, you can try running the following script to reset your codec settings: Note that if you have many sliders, you may have to scroll to the right to see any missing sliders. Run alsamixer and try to increase the value of the sliders, unmuting channels if necessary.
If the problem persists, verify that the Auto-Mute option in alsamixer is set to Disabled. Alternatively, killing the PulseAudio process may cause sound to start working in the desired process.
If it is, try using apulse AUR, as described in Advanced Linux Sound Architecture#PulseAudio compatibility. If speaker-test produces sound but some other program does not, determine whether PulseAudio is being used:
