Just upgraded my machine from fedora fc12 to fc14 and am getting a very loud hiss/buzz in the audio. This hiss is about 2 times louder than the actual audio which can just be heard below the hiss. video is OK.
Card: PVR-150 Input: S-Video/line 1 (not using tuner) players: mplayer /dev/video1 and mythtv both show the same problem. fc14 kernel 2.6.35.10-74.fc14.i686.PAE (1.4.2 ivtv): loud hiss Booting fc14 with the old fc12 kernel 2.6.32.26-175.fc12.i686.PAE (1.4.1 ivtv): sound perfect. fc14 kernel 2.6.35.10-74.fc14.i686.PAE plus latest git://linuxtv.org/media_build.git build installed: Same loud hiss. I've compared the ctrls settings between 1.4.1 and 1.4.2 and the appear identical. Also have tried the set-audio-input=1 option, which I had used previously to get rid of the old tinny sound issue, but no fix. Does anyone know a solution to this issue?
