Title:
[USB powered AudioHub speakers] Burst of noise before playing sound
Status in “pulseaudio” package in Ubuntu:
Invalid
Bug description:
Ever since the upgrade to 3.5.0-15 I'm getting a burst of noise from
my USB powered AudioHub speakers. It happens just before a system
sound is played as well as when launching an audio player, including
suchi. After the initial burst, sounds of all kind play normally.
I've tested it on my 64 bit partition as well with the same result.
I don't know if it's pulseaudio causing the problem and it doesn't
affect my internal speakers.
