Public bug reported:
I'm getting an annoying popping sound whenever pulseaudio gets a new
connection or a connection dies. This is especially annoying since
google chrome seems to open new connections rather often for no apparent
reason, interrupting music playback with glitches.
Steps to reproduce:
1. Start playback of some audio with totem or similar
2. Play a silent audio file with paplay silence.wav, I got mine from audacity
3. Observe pops in the playback from totem
Interestingly there are no pops if I use paplay instead of totem for
step 1. Attaching debug output from pulseaudio -vvvv during the
reproducer above.
My sound card is a USB DAC:
card 3: DAC [UAC1 DAC], device 0: USB Audio [USB Audio]
