Audio BursT

I am facing audio bursts (hi volume “white noise” for a couple of sec) on LibreElec while it worked flawlessly for weeks.

Even on GUI events ? Audio is coming out UsB HiD (which has been checked on other device), I test an other UsB SounD CarD ( ti ) and it's same. Any clue ?

I will update page on investigations

Misc:
