Strange sound issue

Softer · 2010-01-08 19:18:30

Hello, i need some help again. I have strange bug with my sound on netbook (msi wind u100). I've installed alsa, configured it, everything was fine until reboot, after that there was no sound. Alsamixer shows that channels are turned on, not muted, but... The strange part (at least for me) started than i've mute and unmute headphones in mixer. After turning headphones on again sound works again. Until reboot. And this happens every time, i should turn off headphones and turn on again to have sound. That's not big deal, but... It's interesting to know for me why it happens. I've tried to save mixer to /etc/asound.state, but it wont help. btw, this is it:

I'll be happy to see any idea about this, and if i should put any files here, just tell me (i'm not sure, what can be usefull actually). Thanks

After you set your alsa control do this as root:

alsactl store

That saves your settings.

i mean that by "I've tried to save mixer to /etc/asound.state, but it wont help"

I've tried. Same thing after reboot

Is alsa in your rc.conf daemons list?

Softer · 2010-01-08 19:41:45

Yep. Hm... will it work after mute\umute without daemon?
my daemons: DAEMONS=(syslog-ng network netfs crond alsa hal gdm)

OT :: WHAT??? No backgrounding of daemons?

Softer · 2010-01-08 19:54:37

um... i guess that means i should put @ before something? i'm new to linux, so i didint know what actually i should am.... background? I'll search wiki about this later today (i'm at work now), thanks for the correction. Do you think this can be source of trouble?

No no. That is not a solution for your problem. That's the reason I put OT there (Off Topic)

Try Fn-F9 as that might control a hardware mute on the speakers

Just tried. No sound until i'll mute/unmute headphones...

BTW, if i'll mute something else (master or pcm for ex.) or just change (not mute) level of headphones, no sound too... I don't think it's because of any other program i have, because it started after first reboot (aplay /usr/share/sounds/alsa/Front_Center.wav was fine).

+edit:

just tried to delete /etc/asound.state but after reboot mixer didn't reset to default position... maybe there is more places where alsamixer keeps settings? Resaving settings with

alsactl store

didn't make any change

I've find one more thing to think about... Seem's like i've find out why there is no sound, but i still don't know how to fix it. Maybe you'll help me to find out. I've found that if i'll change master volume (even a bit), sound turns off, and it can be fixed only by mute\unmute headphone. Seems like same happens on boot, alsa changes master to stored settings and sounds turns off. Maybe someone have any idea why changing master volume makes sound disabled?
