Please send an alsactl save file with the offending configuration
Attached. I saved this file when the audio was working (i.e having turned the offending control on with alsamixer) but restoring it stops it working.
OK, thanks. I've had a brief look at this here but so far as I can tell I'm not able to see these problems on my system. I am using a completely different machine, though, with different hardware and I haven't checked through your configuration in detail. I'll have a more detailed look early next week.
No unusual dmesg output, the apps think nothing is wrong. It seems that just the offending control (or the actual DACL/R -> SPKMIX mixer channel) stops working. I can still get audio through the
but only via amixer, yes?
One other thing that would be useful would be to put trace which logs the register writes in ac97_write() in the driver and then try testing both using alsamixer and then amixer to do the final enable of the Speaker Mixer PCM Playback Switch.
state.hpipaq214 { control.1 { comment.access 'read write' comment.type INTEGER comment.count 1 comment.range '0 - 31' iface MIXER name 'Speaker Playback Volume' value 1 }
That's rather low...
