Flash sound and LXDE volume control

[topher]

I realize this thread has been posted to death, I have no sound in flash videos in firefox. I was wondering if it has anything to do with the LXDE volume control being stuck at minimum. I can check and uncheck the mute box, but I can't move the slider and the "Volume Control" settings are greyed out. I installed aumix and can adjust the volume level with it. I assume it accesses alsa to do so. Does the LXDE volume control access another sound application?

I noticed that the LXDE panel applet is labled "Display and control volume for ALSA". It must be only showing the Master control which doesn't work with alsamixer either.

Two things you can try --
Install and run alsamixer-gui. (or run alsamixer in lxterminal)
Install and use volumeicon.

thanks Neal, but as I mentioned in my 2nd post the "master" slider in alsamixer doesn't work either. I did manage to fix my problem by enabling ACPI, which I had disabled to use lmsensors. Lmsensors work great with ACPI disabled and sound works with flash plugin in firefox with ACPI enabled. I guess its a trade off: listen to streaming media or monitor my PC's vital signs.
