[alsa-devel] [beagleboard] Audio cap & Linux version 4.1.3-ti-r6.2

Mon Aug 3 17:04:12 CEST 2015

Ok,

some news :

I find out where it's blocked :

I've compiled the alsa-lib, and I've put a lot of printf.

In the file pcm.c, in the function : snd_pcm_wait_nocheck

This line : err_poll = poll(pfd, npfds, timeout);

is called, but I never go out ....

my trace show :

struct pollfd *pfd: 0xbed64780, npfds: 1, timeout: -1

I don't know if it's ok ?

Micka,
