Comment 50 for bug 275998

Copying the information I posted at http://www.pulseaudio.org/ticket/423

Please do submit your test information to the upstream bugreport as well.

I can confirm this bug. It is extremely annoying, since Skype conversations are practically single-way nowadays. Either the receiver hears no sound, very faint sound and most often with a great lag.

If suspending pulseaudio and recording using jack the levels are ok and latency back to a few ms, so it is not a hardware bug.

The only way to workaround this (according to various testers at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/275998) is to remove pulse audio _completely_. Temporarily suspending or killing pulse-audio doesn't help.

Running pulseaudio -v displayed a zintillion of these while making a skype call:
