Your suggested alsa commands seem to have worked. Here is a more detailed response in case the information contained below might be helpful.

Also note that aumix doesn't cover all volume > controls since it's an OSS app. I would think that these new volume controls should be made to default to whatever setting leaves the volume unmodified (usually "100%"), to minimize disruption and to preserve support for pure OSS systems. I would be interested to know if there is some consideration that outweighs this. > Anyway, there is too little hardware information here.

Also, Jeff Garzik's posting about having a similar problem with a chip described by lspci as "Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)" appears to correspond to PCI vendor 0x8086, PCI device ID 0x27d8, which has AZX_DRIVER_ICH. > In most cases, running the following commands solves the mixer issue: > > % amixer set Master unmute 80% > % amixer set Front unmute 100% > % amixer set Headphone unmute 100% Thank you. These commands give me approximately the old volume levels. In particular, the middle command seems to be the one that effected the volume that I could hear. I hope the little bit of information about the PCI IDs that I was able to provide above will be helpful. Thanks again for your quick response. Adam J.
