'Can you post the output of pcm_avail.c when using rate 44100 Hz instead of 48000Hz?
print the time at the same time to check whether the ptr is monotically increasing as expected rate' I attach a file with the specified rate. I don't know/remember C well enough, so I need your help to print the time (in a new attempt). ** Attachment added: "pcm_avail_44100.out" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1551041/+attachment/4596625/+files/pcm_avail_44100.out -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1551041 Title: snd_au8820 0000:01:04.0: BUG: , pos = 16386, buffer size = 16384, period size = 1024 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1551041/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
