Title:
Sound card is muted or mute being constantly toggled when no audio is
played
Status in pulseaudio package in Ubuntu:
Expired
Bug description:
For a long time, Ubuntu has muted the sound card whenever no audio is
played, presumably to save power. On my laptop this has two nasty side
effects. First of all, the mute button LED lights up, even though the
the volume control is not set on mute (in the user interface). Thus,
pressing the lit button does not have the expected effect of unmuting
but the opposite. Secondly, the audio device takes about two seconds
to start up after unmuting, causing short sounds not being heard at
all and the beginning of longer sounds being missing or garbled.
Lately this has getting worse, with the mute status getting toggled
roughly once per second all the time when no audio is being played.
This makes the mute button LED blink in a highly annoying manner, and
it also causes the laptop speaker to click constantly.
On this particular sound device, at least, it would seem best if the
device was never muted for power saving reasons but only when the user
actually has muted audio output.
