Title:
USB sound card not detected: ID 09e8:0010 AKAI Professional M.I. Corp
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
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)
