Thanks Gerry !

I dont run Ubuntu, and currently have another use for my BBB, but I definitely will want to look into this at some point. I will have to adapt to Debian, but should be very close if not exactly the same.

Again, thanks for taking the time to write these steps out.

Why is it necessary to disable the HDMI video and EMMC device tree overlays ?

[6err...@gmail.com]

Hello,

disable the HDMI: read this https://groups.google.com/forum/#!topic/beagleboard/ZJGwxA7BG4E
I dont need hdmi but need SPI 0 and SPI 1

disable the EMMC-2g: is optional, i dont need this in the moment

I want to use my beagle bone black to rip analog signals to my Beagle bone using an audio cape. Does anyone know if I would require a sound card to do so?

Hi Gerry,

I am trying to get a USB soundcard C-Meida to work on BeagleBone Black Ubuntu. My Ubuntu is precise 12.04 LTS (ubuntu-precise-12.04.3-armhf-3.8.13-bone30.img.xz)

 when I open uEnv.txt I see the following which is different from yours.

mmcpart=2

optargs=fixrtc

uenvcmd=i2c mw 0x24 1 0x3e; kd=0; if test $mmcdev -eq 1; then mmc dev 0; if mmc rescan; then kd=1; fi; mmc dev 1; fi; setenv mmcroot /dev/mmcblk${kd}p${mmcpart} ro

loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}

loadimage=load mmc ${mmcdev}:${mmcpart} ${loadaddr} ${bootdir}/${bootfile}

I cannot follow your tutorial since the first step is different. Do you have any ideas what is going on?

Thanks a lot.

Just add
capemgr=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONE-EMMC-2g
Somewhere in the u-boot env. And reboot bbb.
This will disable stereo audio output via hdmi. 
Hope it helps
Priyank.

Hi Thanks for the quick response. 

I tried the solution but it did not work.

This is the procedure that I tried:

1- $ lsusb

Bus 001 Device 002: ID 1a40:0101 Terminus Technology Inc. 4-Port HUB

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 001 Device 003: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter

Bus 001 Device 004: ID 413c:2105 Dell Computer Corp. Model L100 Keyboard

2- $ sudo nano /boot/uboot/uEnv.txt

mmcpart=2

optargs=fixrtc

uenvcmd=i2c mw 0x24 1 0x3e; kd=0; if test $mmcdev -eq 1; then mmc dev 0; if mmc rescan; then kd=1; fi; mmc dev 1; fi; setenv mmcroot /dev/mmcblk${kd}p${mmcpart} ro

loadfdt=load mmc ${mmcdev}:${mmcpart} ${fdtaddr} ${bootdir}/dtbs/${fdtfile}

loadimage=load mmc ${mmcdev}:${mmcpart} ${loadaddr} ${bootdir}/${bootfile}

##BeagleBone Black:

##Disable HDMI/eMMC

#capemgr=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONE-EMMC-2G

capemgr=capemgr.disable_partno=BB-BONELT-HDMI,BB-BONE-EMMC-2g capemgr.enable_partno=BB-BONE-AUDI-01

3- $ sudo reboot

4- $ sudo apt-get install mpd mpc alsa-utils

4- $sudo aplay -l

aplay: device_list:252: no soundcards found...

:( sad

BBB is not seeing the soundcard as you see:(

[robertl...@gmail.com]

Just a tid-bit:

I found that you can specify with a config file which sound card to use:

create a file /etc/asound.conf

pcm.!default sysdefault:Device
