Why is the pavucontrol level indicator jumping while nothing plays?
- by EnterTheLiquidToasterFamily
The level indicator in the screenshot
does jump around even if nothing is playing.
The indicator also reasonably represents sound levels when music is playing.
I dont have any mediaservers running or noisy browsertabs open. Also no mic connected.
When I turn the volume to max in software and on the amp, there is no noise from the speakers at all. Played music is loud and not distorted.
Hardware: Realtek ALC889 over optical audio connector to a generic amp.
Software: Debian Wheezy with latest backport kernel 3.14 (same thing on wheezy 3.2 stock), wheezy pulseaudio, xfce session, a custom asound.conf that enables pulseaudio to push sound over optical port.
/etc/asound.conf
pcm.a52 {
@args [CARD]
@args.CARD {
type string
}
type rate
slave {
pcm {
type a52
bitrate 448
channels 6
card $CARD
}
rate 48000 #required somehow, otherwise nothing happens in PulseAudio
}
}
