Panic, when playing music

Great, that is good news! :)
Then I suppose the dropped frames over that time is nothing to worry about - frames may be dropped unexpectedly from time to time due to RF noise or changes in the physical environment, but as long as it only happens as seldomly as it does in this case it should be no problem at all.
Thank you for sharing the test results with me nevertheless!

Please do not hesitate to open another ticket if you should encounter any other issues or questions in the future.

Good luck with your developing! :)

Best regards,
Karl

Hi，Karl

Sounds ok, no noticeable artifacts

thanks

Hello again,

Could you describe the test setup and environment? What are between the two devices, and how is the RF noise in the environment?
5437 bad frames in the span of 9 hours equates to less than 0.0016 of frames being bad. Was there ever any audible artifacts caused by this?

Best regards,
Karl

Hi, Karl

i have add a counter for bad frame, and after more than 9 hours testing, I got following information:

HL [09:08:46.645,050] <dbg> audio_datapath: audio_datapath_stream_out: Bad audio frame: 5437

the number looks a bit too much

thanks

Hi, Karl

ok, next we will test the LC3 codec

thanks

Thank you for the update - I am glad to see that you were able to test for 8 hours continuously with so few bad frames / issues.

Please do not hesitate to open a new ticket if you should encounter any issues or questions in the future.

Good luck with your development! :)

Best regards,
Karl

Yes, that should suffice.

Let me know if you still experience this issue following the change!

RE: Panic, when playing music

Hi, Karl

RE: Panic, when playing music

Karl Ylvisaker — Wed, 15 Jun 2022 09:20:38 GMT

Hello again,

The behavior you describe in your ticket is something we have seen before when using the SBC codec. In essence, it is caused by sw_codec_select not handling the SBC's output properly when a bad frame occurs.
As a quick fix for this I suggest that you just remove the ERR_CHK_MSG on line 815 in this case - at worst this could sometimes produces audiable artifacts when a bad frame occurs with the SBC codec, since ctrl_blk.decoded_data contains the data from the last frame/package, which means that the same frame will be played twice.

Please try this, and let me know if it resolves the issue.

Best regards,
Karl

RE: Panic, when playing music

Zhongsan — Mon, 13 Jun 2022 13:10:07 GMT

i am sure i have remove that from both overlay-headset.conf and overlay-gateway.conf

thanks

RE: Panic, when playing music

Karl Ylvisaker — Mon, 13 Jun 2022 12:57:33 GMT

Hello,

It seems that the data received is reported as the wrong size, which causes the operation to cancel.
Have you made any other changes to the reference application than those you have listed at the beginning of your ticket?

I notice that you are using the SBC codec, could you confirm that you have also removed the following:

CONFIG_LC3_ENC_CHAN_MAX=2
CONFIG_LC3_DEC_CHAN_MAX=1

from overlay-headset.conf and overlay-gateway.conf?

As a side note I would also like to recommend that you use the LC3 codec for your evaluation if possible, since it significantly outperforms the SBC in all aspects for the common audio use-cases.

Best regards,
Karl
