Dell Mini9: Audio hiss with headphone on Karmic
When you put headphone jack in an hissing sound starts from speakers, if you remove headphone the noise stops immediately. The sound in headphone is quite perfect.
I'm on a dual boot machine (9.04 and 9.10), with jaunty with kernel 2.6.28 sound is perfect with no issues. Audio settings are the same on both OS. I suppose it's a pulseaudio/kernel settings related problem (Karmic now uses 2.6.31-14 kernel) but can't be sure.
Tested it with mics muted and all audio set to zero. No luck.
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
Could someone confirm this issue on Mini9 before I start a bug on launchpad?
