I'm currently struggling with the BeagleBone Audio cape on a BeagleBone
black. I keep getting ALSA buffer xruns when capturing audio. Has anyone
successfully done any recording using the audio cape and if so how did
they do it?
I am currently running 3.13-rc7 mainline and I was experiencing the same
behaviour on 3.8. Recording to a uSD card is worst, then eMMC and I have
even seen buffer overruns when recording directly to tmpfs once or
twice. I am worried that it may be a problem with the audio driver, or
something is blocking interrupts for too long and the interrupt to empty
the ALSA buffer is being missed.
Does anyone have any input?
Cheers,
