Mavlink PLAY_TUNE message does not play tune

[wluker]

Describe the bug
Sending a tune string "MFT200CDEFGAB" via a PLAY_TUNE mavlink message does not produce any sound on the drone.

From the fix for #12059 I can produce sound with "tune_control play -m "MFT200CDEFGAB" ".

The PLAY_TUNE mavlink handler is implemented in https://github.com/PX4/Firmware/blob/4831a4b0cfde499eb1a20257cc46b130e6554e3a/src/modules/mavlink/mavlink_receiver.cpp#L1627 and I am sending the correct message because this triggers, but it doesn't produce sound.

To Reproduce
Steps to reproduce the behavior:

1. Drone switched on '...'
2. send PLAY_TUNE mavlink message with "MFT200CDEFGAB" in PLAY_TUNE.tune
3. Listen for sound

Expected behavior
A tune should be played.

Drone (please complete the following information):

• Pixhawk2 with latest firmware from git

Hi @wluker , if I issue the command tune_control play -m "MFT200CDEFGAB" from the mavlink console in QGC the tune plays correctly for me on fmu-v2 and fmu-v5.

I think we can close this issue, but if I am not understanding your issue or this is still an issue for you would you please re-open? Thanks!

Hi @mcsauder

Thanks for looking into this. This issue is not in tune_control play -m "MFT200CDEFGAB" because that plays for me as well. The issue is that you can't trigger any tune via the mavlink message PLAY_TUNE. https://mavlink.io/en/messages/common.html#PLAY_TUNE

I was trying to send that message via an offboard controller, but no tones were being played even though I could tell PX4 was receiving the message. Maybe I am misunderstanding the intended use of the PLAY_TUNE message.
