I have a similar problem and setup, but there is no way for me to control the muting it seems from the audio control. lspci gives me this setup:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) It's a built in sound devince on a Dell Precision M65. However, when I fiddle a little with the Volume Control, setting the Input source combo to Line and then back to Mic again, + closing the Volume control: HDA Intel (Alsa mixer), then grabbing seems to work again. -- Unable to record sound with an Intel 82801DB-ICH4 sound card https://bugs.launchpad.net/bugs/16067 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
