A few months short of THREE years later, this issue is still there in Ubuntu 14.04 .
I see the iMic when I hotplug it, but only as a device. Pulseaudio does not assign it to either sink or source (while the device provides both). Using pavucontrol I do see 3 possible configurations in the configuration tab: stereo, mono and off. But those don't serve a purpose. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/980153 Title: Hotplug of iMic USB soundcard does not always produce a viable audio output --Precise upgrade Status in pulseaudio package in Ubuntu: Confirmed Bug description: Problem: Hotplug of iMic USB soundcard does not always produce a viable audio output on Precise upgrade Steps to reproduce -boot up with iMic plugged in -unplug iMic -wait a minute -plug the iMic back in -select the iMic as output in the system sound preference pane Result -no audio via iMic -audio continues via build in speakers Expected results -audio via iMic -audio via build in speakers should cut off Work around: Runs fine if the computer has booted with the iMic plugged in. or reboot with iMic plugged in iMic hardware details: Griffin Technology, Inc iMic USB audio system, the earlier model if I recall. The following terminal command apparently reveal only the internal sound card. dmesg | grep sound HDA Intel SPDIF Both lsusb | grep audio and lsusb | grep sound don't retrieve any info, which is odd because the system sound preference pane lists the iMic device as an output.
