[meta-freescale] PulseAudio abort with BT/A2DP disconnect

[Takashi Matsuzawa]

Hello.
Correction:   I re-tested and confirmed even for me the below 2 patches were enough to prevent the A2DP crash.

"Fix: Prevent calling pa_rtpoll_free() for a NULL rtpoll"
"thread-mq: Make pa_thread_mq_done more robust"

Hello.

I further looked into, and turned out that the issue is essentially the same as below.


https://bugs.freedesktop.org/show_bug.cgi?id=89672

Though the two patches mentioned there was not enough to solve my crash, and I still needed to prevent stop_thread() code to be recursively called, as mentioned in the proposed patch mentioned there.

Hello

Thank you for your information, It might be PA 9.0 but so far I did not tried yet.

PA9.0 still seems to have similar issue but for A2DP source scenario, and I am thinking to look into its fix when it is available.

(https://bugs.freedesktop.org/show_bug.cgi?id=96831)


What I am seeing now is that if it causes segfault, PA daemon is restarted and from user-point of view it look normal (though there is a short period of no PA running).  If it causes assert (instead of segfault), PA dies and need restart (manually or by board reboot).

This happens in PA's asyncmsgq code..

We have this working for a customer but based on Krogoth. It works well for him.
