Hi,
I am evaluating the nRF5340 Audio DK by applying the sample code nRF5340_audio.
I tried changing the frame to 7.5 ms by editing prj.conf as below and no audio came out of the headset.

# nRF5340 Audio
CONFIG_NRF5340_AUDIO=y
CONFIG_AUDIO_DEV=2
CONFIG_TRANSPORT_BIS=y
CONFIG_TRANSPORT_CIS=n
CONFIG_AUDIO_SOURCE_USB=n
CONFIG_AUDIO_SOURCE_I2S=y
CONFIG_AUDIO_FRAME_DURATION_7_5_MS=y
CONFIG_AUDIO_FRAME_DURATION_10_MS=n
*For the headset, set CONFIG_AUDIO_DEV=1.
Also, when I changed the gateway's audio source to USB (CONFIG_AUDIO_SOURCE_USB=y, CONFIG_AUDIO_SOURCE_I2S=n), the center LED turned red as soon as the audio was input.
It works fine if the frame is 10 ms.
Is 7.5 ms frame not supported?
I used 2 PCA10121 boards (Gateway/Headset), NCS v2.1.2, sample code "nRF5340_audio".
