Hello, I plugged in a C-Media 7.1 sound card in the BBB with Ubuntu 13.04 (SD card boot). Everything looks allright but there is no sound. Also the C-Media didn't become the default sound driver.
Please help. I did the following: ================================================================================= Step 1: ubuntu@arm:~$ sudo apt-get install alsa-base alsa-utils alsa-oss Reading package lists...
