audio trouble with BeagleBoard-xM

Peter Kurrasch

I can't seem to get any audio out of my BeagleBoard-xM, rev. C, when using the kernel 3.2 version of Angstrom.  If I run a kernel 2.6.32 version of Angstrom the sound works fine.

I'm using just aplay and speakertest to keep it simple.  By all appearances the software is happy to produce the audio,except that nothing comes out (I'm just using the headphone jack--nothing fancy).

Is there some diagnostic I can/should run to confirm that the twl4030 driver is properly built and/or the tps69590 properly configured?

Does anyone know if the audio drivers are known to work on kernel 3.2 on the BBXM?

I'm happy to provide more info--just not sure what else would be useful at this point.  Thanks!

    Hi Peter,

    It seems that the problem is due to the new kernel 3.2 or probably to configuration which you are using.

    Are you using stored config file for the kernel building and if it is that could you specify which one or you make manually configuration using menuconfig or something else?

    About the diagnostic: You could use logcat command for obtaining detailed debug information.

    Hi Tsvetolin--

    I thought logcat was just for Android?  Either way, I don't have it on my particular Angstrom build.

    I'm inclined to agree with you that something is just wrong with the 3.2 kernel.  I'm using the 2012.05 release/distribution and am using the default config to build everything.  I'll probably wait until the next release which I think will be 3.7 (I think).

    Any idea if the audio stuff is tested/working with kernel 3.7? I saw a comment somewhere that it wasn't yet tested but don't know for sure.

    Thanks
