Description Warren Togami 2009-01-29 16:02:16 EST
Fix default setting of ALSA hardware volume.  This worked earlier, but it broke after we added alsa-plugins-pulseaudio to the chroot to allow localapps to use sound.  alsa-plugins-pulseaudio redirected the default ALSA output to pulseaudio instead of hardware.

Impact:
It was impossible to increase volume to an audible volume with most hardware.

Fix:
Add -c0 to calls to amixer so it directly sets the first ALSA hardware device.
All hardware channels are increased from 55% to 90% by default.

WARNING: This triples the default software volume and will be a big surprise if your speakers are maxed out.

ltsp-5.1.55 will be the first build with this new behavior.  You must update ltsp-client in the chroot.
