Hi,

If I use mplayer command line to play mp3 file like this:

mplayer -ao alsa1x:hw:0 test.mp3

The song is playing; And if I use "/" or "*" to increase/decrease
volume, got the error message:

[alsa-control]: unable to find simple control 'PCM',0 

Is something wrong with my alsa driver or something else? I checked I
installed 2 RPMs related to ALSA:
alsa-lib-1.0.3a-2
alsa-utils-1.0.3-1

Any one have any idea?

Thanks.

Rocky

Hi,

I download latest Mplayer to my computer (Fedora 2). And I connected 1
Labtec USB headset, and config Mplayer to use ALSA sound drive. The
problem is I can't control the volume of playing movie. I drag the
volume button to right, after I release my mouse, it go back to the left
side. Is there any configuration I can modify to make it work?

I test another audio application -- Xmms, in it's preference there is a
checkbox for "Software Volume Control", after I check it, I can control
my volume when I play songs. 

Anyone else can help me?

Thanks.

Rocky
