I have been trying for many weeks to solve this problem, but with no success. After updating to Alsa 1.0.17, which include changes to aloop, I still have choppy audio. I will try to summarize what happens:

- I need to use aloop, if I change to a sound card all the problems are gone; - After some time of continuous play, applications start to reproduce choppy audio. Choppy audio doesn't happens all the time; - If I repeatedly start and stop my sound capture application choppy audio occur sooner; - Start/stop my application restores the sound quality (after some tryies); - This happens with ALSA applications (xine, vlc) and OSS emulated; - I have tryied many period_size and buffer_size in asound.conf, now I am using 960 for period and 3840 for buffer. As I decrease period size, the audio quality improves, but choppy audio still happens; - I test for overrun but no errors occur. - I am using block mode, interleaved, 44100, 16 bit, 2 channels - I am using dmix, dsnoop, removing them does not correct the audio

These are some of the information I have, I don't know if is is enough. If necessary I can provide any other information. What do you suggest that I do? Are there any known issues or configuration requirements?

Thanks in advance.
