When i change PCM level to zero (neither Master, Headphone) it affects sound level, so it cannot affect sound crackling phenomena.
Front channel affects only internal speakers, so it cannot affect crackling. Surround, Center, LFE channel doesn’t seem to affect volume level neither internal nor external speakers. May be there should be a solution. But it seems that the problem affect linux kernel or wake up processes because after hibernate sound starts to crackle. -- Sound buzzing (crackling) for sound Intel Corporation 82801G (ICH7 Family) https://bugs.launchpad.net/bugs/296310 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
