I've also had crackling and popping problems with pulseaudio ever since I started using it about a year ago. I've got a regular Intel sound card in an Ivy Bridge laptop.
After about a year of ripping my hair out, I finally tracked my problem down. /etc/pulse/default.pa Try setting load-module module-udev-detect tsched=0 Then rebooting. That completely fixed it for me and it's been weeks and I haven't heard a single crackle or pop. I was hoping if you could give it a try and report back to see if that was your problem as well. It looks like this is a very common problem. -David -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
