Nrf54L15 support LE Audio?

[Reskyllr]

Hi,
We are evaluating whether nr54L15 supports LE Audio function?
According to the specification, it supports bluetooth 6.0 and should support LE Audio (Isochronous channel). Please give me an accurate answer.
We currently have an application using nrf5340 audio. For some reasons, we want to migrate to nrf54L15. Is there any risk in doing so? Do you have relevant samples to provide?
Thanks,
Best regards

Hello,

The nRF54L15 doesn't have something called Audio PLL. Hence, it is not ideal for audio streaming (at least of multiple channels). As it is today, the nRF5340 is still our best choice for Audio over Bluetooth LE.

Hi Edvin,
Additional explanation:
Based on our experience, classic audio does not rely on Audio PLL. Why is LE Audio necessary? Is it because of Isochronous channel?

Is this internal to the chip? Can I use it if I add it on the periphery?

It is internal, yes. It is used to sync up the timing of the I2C streams, to avoid drifting in the sound stream (which will result in cracking sound or pauses, because the sound is played too fast or too slow).

I am sorry. I don't know. I have no experience with Bluetooth Classic. 

From what I understand, acting as the source of the sound will be possible in the future (not yet implemented). From a software perspective, the SoftDevice Controller (Bluetooth Low Energy stack) supports (or will support) isochronous channels.
