I am confirming this problem. I tried using ALSA:default as the audio output. Here's the status of the relevant Alsa volume levels:
Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 28 [90%] [on] Front Right: Playback 28 [90%] [on] Simple mixer control 'PCM',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 28 [90%] [on] Front Right: Playback 28 [90%] [on] Simple mixer control 'Line',0 Capabilities: pvolume pswitch pswitch-joined cswitch cswitch-exclusive Capture exclusive group: 0 Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 9 [29%] [off] Capture [on] Front Right: Playback 9 [29%] [off] Capture [on] Simple mixer control 'Capture',0 Capabilities: cvolume cswitch cswitch-joined Capture channels: Front Left - Front Right Limits: Capture 0 - 15 Front Left: Capture 8 [53%] [on] Front Right: Capture 8 [53%] [on] This all is running on a dual processor AMD 768 motherboard. relevant parts of lspci: 02:04.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) 02:04.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) 02:05.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 0a) Tuner I use is Hauppauge WinTV Plus (software encoder). I switched from Gentoo where this problem did not exits. All old recordings play fine and at a much lower volume level. New recordings play with a buzzing sound (as if there was high pitched "noise" in the signal) and cracking sounds when people speak, etc (as if it were poorly digitized). I checked various settings within mythtv: sound is recorded as MP3 at 9 quality at 48000 sample rate at 90%. I'll try to upgrade to fiesty and see what happens... I'll post my experiences here.
