Re: eeepc 1001px - Sound issue (no sound at startup and master sound wrongly mapped)

You can use the command line to send alsa commands, this can be useful if you need to run something at startup if it wasn't working very well. If I remember correctly, tracing what those do is quite simple because they very quickly end in sending an ioctl command to the kernel driver. So most probably, if the headphone and main speaker is switched on certain hardware, it could be something to do with the kernel driver. What controls the volume on the actual headphone socket if you had 'phones to try? It might be worth checking if the correct driver is being loaded and whether there is some module command switch to adjust it.
I'm using alsa and no pulseaudio with alsa-utils-openrc enabled in default and it remembers my settings. I'm in the "audio" group too.
(But I am not using an eee.)
$ amixer set Headphone mute
$ amixer set Headphone unmute
If alsa believes it is already unmuted it won't send a command to the driver, I had a situation once where audio was muted at boot but it showed as unmuted in alsamixer, so I ran mute then unmute in a desktop startup script. I'm not sure how much of this would be relevant if you had pulseaudio installed as well though.
