Public bug reported: On Ubuntu 12.04 x64 using kernel 3.11.1-031101-generic (which supports USB audio), I am able to get one of two USB audio devices working (Turtlebeach AudioAdvantage Micro = CM102-A+/102S+ Audio Controller, lsusb ID 0d8c:0103) . This proves snd-usb-audio is loaded and working.
The device which is not working (reason for this bug report) is an AKAI EIE Pro. Per lsusb, it has ID 09e8:0010. However, when plugged in, it does not show up with cat /proc/asound/cards . The same USB audio devices operates fine on the same system under Windows 7 x64, proving it's not a HW problem or a 32 vs 64 bit issue. lsb_release -rd Description: Ubuntu 12.04.3 LTS Release: 12.04 AlsaMixer v1.0.25 Expected behavior: plug in EIE Pro USB audio device and have it show up in alsamixer (and in Unity's sound selection GUI) Actual behavior: plug in EIE Pro and device does not show up in alsamixer or in sound GUI (ie PulseAudio Volume Control) ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: alsa-base 1.0.25+dfsg-0ubuntu1.1 Uname: Linux 3.11.1-031101-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version k3.11.1-031101-generic.
