Dear altruists,
I'm writing a sound card driver based on ALSA API. My driver works perfectly on Ubuntu 12.04, 13.10 and 14.04. There is no problem on how many times I play a sound file using my driver. Everything works great. But same driver has some issue on debian distribution.
I've been trying to test it on BeagleBone and during the first run the driver works pretty well. But as soon as I play a second sound file, it crash. I thought may be I did something wrong in releasing resources after 1st run. But so far from my debugging it looks like there is no problem with resource release. Also same driver works on Ubuntu as many times as I test. I even tested with the same sound file. On debian, I get the following message is kernel log-
Apr 23 20:26:41 beaglebone kernel: [ 183.631905] ALSA sound/core/pcm_lib.c:1910 playback write error (DMA or IRQ trouble?)
It would be highly appreciated if I can get some suggestions on which direction I should try to resolve this issue. Is there any known issue with debian distribution or anyone faced similar kind of problem before?
Thanks Azizul Hakim
