It works just fine.
For an SBLive!...well, there's about fifty-odd different channels on the SBLive!. If you start up alsamixer and pan to the right, you'll see all of them. It's quite a daunting collection of channels, but fortunately, you'll probably only use a few of them. Also, something that might not be obvious from looking at alsamixer is that the channels can be muted two ways. The first way is to set a "mute" flag in the mixer hardware; the second is to just turn the volume all the way down. Either method will effectively mute that channel's output, even of only one of the two methods is used; both can be used at the same time. Basically, if you see an "M" character at the top of a channel bar in alsamixer, that means that channel's had the mute flag set in hardware. You should be able to just get the cursor on that channel and press "m" to clear that flag. If you don't want to have to play with the mixer settings every time you load the modules, use alsactl to save and restore the mixer state. If you have a SysV-style init (like RedHat, SuSE, or any LSB-compliant distro), the "alsasound" init script (usually located in /etc/init.d or /etc/rc.d/init.d) can take care of running alsactl automatically on system boot and system shutdown. -- Kelledin "If a server crashes in a server farm and no one pings it, does it still cost four figures to fix?" ------------------------------------------------------- This sf.net email is sponsored by: OSDN - Tired of that same old cell phone?
