New Revision: 2101
Modified:
trunk/packages/alsa-utils/set-alsa-volume
Log:
Made "Playback" a PCM-like control (i.e., always at 74% or 0dB),
because of SB16. Made the "volume=-15dB" boot argument work.
FIXME: some USB audio cards have none of the "Master", "Front" and "Headphone"
controls. It is currently impossible to set the volume from the command line
on such cards. Help wanted from hardware owners.
