Hi, Dear developers I encountered a hang issue when I use ALSA together with a2dpd.
Environment: Setup Bluetooth-alsa environment (including .asoundrc, .a2dprc), so that Bluetooth earphone works Symptom: Occasionally(about 15% percentage), after finished playback one song, then I open another song, this time I can't hear music and finally hang. This issue does not always happen, sometimes even I finished playback almost 10 songs, this issue didn't happen, sometimes after played 5 songs, issue happened. Some investigation I did: 1. I could locate the code where causes the hang. It is an ALSA API snd_pcm_prepare which is located at CAudioOutLinuxAlsa::_Reset(). 2. firstly I doubted root cause may be at alsa or a2dpd layer, then I downloaded and built out alsaplayer, it turns out alsaplayer does not have this issue. 3. I also tried change alsa configure file and make audio direct to normal audio out rather than a2dpd, then this issue does not happen. Could anybody tell what may cause this issue? Thanks a lot!
