Playback music will fail in sometime

[zoechen]

Dear Fsl,

     I use IMX6Q, android 4.4 to test the music function and found there is a bug when we playback songs. We can re-appear the bug as follow step:

click play button to playback one song -> click pause button to stop the song , repeat the two step again and again. The music playback will be fail. I check log, found the reason is system do not wake_up(&runtime->sleep) in kernel_img/sound/core/ . Do you have any idea for this? I will continue to track the code, bug I want you can give me some idea.

Thanks,

Zoe Chen

Hello Zoe,

Can you let me know the exact android version you are using, and if it is on our SABRE Board ?. Is there a specific file lenght or extension to play?

Hi FSL Support Team,

We use Android KK, our board is based on SABRE Board, the music

file is a normal file. Now I can't understand what will effect DMA

transfer or what will effect trigger DMA interrupt after transfer finish

? BSP or hardware? I think BSP is ok beacause this issue is a small

probability event.

BR,

Zoe
