having same problem - bug 656466 - also Realtek chip; but different model, and Ubuntu 10.10 instead of 9.10 as here.
I see from the debug output that your line control is also muted and the volume set to 0% Simple mixer control 'Line',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 0 [0%] [-34.50dB] [off] Front Right: Playback 0 [0%] [-34.50dB] [off] I fixed it on the command line - applications -> accessories -> terminal your TV card is also seen as an audio card so you will need to specify which audio device to control check by running: amixer -c 0 sget 'Line',0 If that doesn't work, try amixer -c 1 sget 'Line',0 Assume device zero, you can unmute the Line In and set the volume as follows. run the second command with higher percentages if required. amixer -c 0 sset 'Line',0 unmute amixer -c 0 sset 'Line',0 25% If it doesn't work, set it back. amixer -c 0 sset 'Line',0 mute amixer -c 0 sset 'Line',0 0% -- Line-in input is not forwarded to output device https://bugs.launchpad.net/bugs/502685 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
