Hi all,

I'm new owner of UBOOM L speaker and I have noticed crackling sound on high volumes.

The issue exists on 0.50 and 0.48 firmware, also on video low latency mode and normal mode.

The speaker is connected via bluetooth to my phone and audio sources are Tidal and Youtube.

Can I do something?
