No sound is played on notification received

[miggat]

When a new notification is received it is properly displayed on screen and the device vibrates, but there is no sound at all. I sticked it to my ear to make sure it wasn't an audition problem on my side.

Here's what I can see on the serial monitor:

I (567777) WS: WEBSOCKET_EVENT_DATA

Let me know if I can provide further information to diagnoze the issue.

From log it looks like it is working properly as no issue is there. The problem with I2S in case of TWatch is that it's fire and forget way of doing it. It works fine on my watch, but I had issues playing sounds long time ago. So I left the watch for a day or two with battery removed and after that it started to play the sound again - no code change or anything.

Also you can try this sample: https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library/tree/master/examples/BasicUnit/PlayMP3FromPROGMEM to make sure there is no bug in TWatchSK. Run it on your watch and let me know if you hear audible sound.

Please keep me posted!

Thanks, Jan

I'm afraid i'm not skilled enough to test that example (TTGO_TWatch_Library fgails to build because some xtensa related issues that i don't understand) but i tested the factory firmware (https://github.com/sharandac/My-TTGO-Watch) and when i trigger an alarm, sound is properly played, and definetly loud enough. I assume this proves that at least the speaker is working.

Uploaded TWatchSK again, and still, same output as the original post, but no audible sound.

I'm not using the watch for any real-life scenario currently, so happy to help debugging if you give me some guidelines.

Fair enough, if other firmware works fine on your watch I'll need too look into this! Thanks!

Just FYI, I manage to build and install the suggested sample (https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library/tree/master/examples/BasicUnit/PlayMP3FromPROGMEM) and confirmed sound is playing.
