My sound card supports surround and I've noticed that if I switch the output to that and back to stereo, the problem disappears for a while (making me think it's a buffer issue). It also works with switching to the sound card's digital output, but causes an audible pause in sound.
To do this for me when the sound starts crackling, I've added a launcher to Unity that simply has this as its Exec line: sh -c "pactl set-card-profile 'alsa_card.pci-0000_00_14.2' 'output:analog-surround-40' ; pactl set-card-profile 'alsa_card.pci-0000_00_14.2' 'output:analog-stereo'" This of course only works on my computer due to the PCI address, but the concept should work in general. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/444950 Title: sound stops working with pulseaudio -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
