SPL:0dB when recording video with GoPro Hero 11 firmware v2.30.70 March 2024

[compoundvpn]

On Labs firmware prior to v2.30.70 for the GoPro Hero 11, SPL displayed on screen a non-zero value when recording video.

On the latest March 2024 v2.30.70 release, it displays a fixed value of 0 from the start, and during video recording sessions. Battery removed, re-installed and same issue.

Steps to repeat the bug with Labs v2.30.70 installed:

STEP 1 - !RESET - Reset all permanent metadata
STEP 2 - !FRESET - Factory reset the device, connect to GoPro app on phone, pair
STEP 3 - !MAUDS=1 - Display approximate audio levels

SPL displays 0 all the time.

Camera was reset to ensure no other actions/commands or malformed commands affect the issue.

Are you able to reproduce the bug on your side?

Confirmed. This is also broken on HERO12 too, but as no one reported that error, is it was ported to H11 with the other H12 enhancements. The SPL trigger works, but the SPL display does not.

A crude workaround, scan:

This will turn on and keep the audio monitoring active.
