Problem #1: Flash videos 'steal the sound' from other applications.
I fixed this by setting up alsa to use pulseaudio by default. I might need some more testing to see if it actually fixes the problem. To fix:
1. Open a root terminal and create a file called /etc/asound.conf
Code: Select all
nano /etc/asound.conf
Code: Select all
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.!default {
type pulse
}
ctl.!default {
type pulse
}

Problem #2: Changing volume per application does not work. (For example changing the volume icon in Rhythmbox makes the system volume change).
To fix this just change a setting in /etc/pulse/daemon.conf about flat volumes.
1. Open a root terminal and run:
Code: Select all
nano /etc/pulse/daemon.conf
Code: Select all
; enable-lfe-remixing = no
flat-volumes = no
; rlimit-fsize = -1

Problem #3: ALSA problem where some channels in 5.1 surround seem really quiet.
Not strictly pulse related I think the way to fix this is to enable downmixing. I do not have many surround files so some feedback would be helpful. Please note you nee libasound2-plugins package installed for this to work.
1. Open /etc/asound.conf again.
Code: Select all
nano /etc/asound.conf
Code: Select all
pcm.!surround51 {
type vdownmix
slave.pcm "default"
}
Hopefully these help some folks!
