No sound out of headphone port
- by Thanatos
I cannot get sound out of the headphone port. Headphones are plugged in, and sound comes out of the internal speakers. Windows behaves normally (sound switches to headphones when headphones are inserted).
It did work in Linux at one point, but something changed, we're just not sure what. Rebooting doesn't fix. This appears to occur whether or not PulseAudio is running.
Things I've tried:
Rebooting. No effect.
Booting into Windows. It works properly, so probably not a hardware issue.
All of alsamixer. My only controls are this:
"Master" Volume bar & mutable, unmuted. Controls volume.
"PCM" Volume bar only. 100%.
"S/PDIF" Mutable only, currently muted, has no effect.
"S/PDIF" Default PCM", Mutable only, currently unmuted, has no effect.
Killing PulseAudio. No effect. (It also won't stay dead! Something appears to be restarting it, and I can't tell what, but it is annoying as fuck.)
alsactl init 0, no effect.
sudo rm -f /var/lib/alsa/asound.state, no effect.
General system info:
Ubuntu 10.04 LTS
Toshiba Satellite T135D-S1324
