I'm experiencing the same hissing noise (no clicking whatsoever, but this seems unrelated anyways) on the center speaker as well. I'm using the onboard soundcard of a Gigabyte GA-P35-DS4 (chip is an ALC889A):
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02) Subsystem: Giga-byte Technology Unknown device a022 Flags: bus master, fast devsel, latency 0, IRQ 23 Memory at ea200000 (64-bit, non-prefetchable) [size=16K] As long as not both the front and the surround channel are muted, the center speaker emits that hissing noise (even if center itself is muted). I'm running the an up-to-date Gusty with kernel 2.6.22-14-generic. -- Creative SB Live 5.1 - Center puts out hissing, and Front has a clicking noise https://bugs.launchpad.net/bugs/151947 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
