nRF5340 SDK update from 2.6.1 to 2.7.0 test tone volume

[adunk]

I used the nRF Audio Example to build a BLE audio device. I use the test tone generator functionality. I was previously using nRF Connect SDK 2.6.1 and the test tone generation functionality worked straight out of the box where I would pass the frequency, duration, and the amplitude (float between 0-1). I have recently started porting the SDK to 2.7.0. Everything was fairly straightforward excect for the test tone generation functionality. I seem to have no control over the volume. It always plays at an extremely loud level regardless of what amplitude I pass into the test tone generation functionality. Any ideas on this? I don't see any notes in the migration guide related to this feature.

Thanks!

An update, although the test tone is loud, the problem appears to be related to the i2s. When I connect the BLE device, the audio is always extremely loud. This audio is transmitted over BLE, not related to generated from the test tone.

Hello, 

The default volume can be changed in the audio driver, by editing OUT_VOLUME_DEFAULT. 

Let me know how that works for you!

Kind regards,

I found the issue. I had to change the I2S Formatting configuration from its default configuration. It was causing all audio to be loud and distorted. Thanks!

That is good news! Glad you we're able to find the solution.
