Hi,

[don't forget to Cc me]

I've got a Dell Precision 390 workstation, onboard sound running with snd-hda-intel module.

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) 00:1b.0 0403: 8086:27d8 (rev 01)

When audio is output using the OSS interface (mpg123 or mplayer -ao oss), output is overly loud and the PCM mixer control has no effect.

Master tuned in to 13% (alsamixer says dB gain=-40.50) is about the level as when using the ALSA interface running with Master 58% (dB gain=-19.50) with PCM 63% (dB gain=-19.50).
