[PROBLEM] Crackling audio when playing 5.1 FLAC over HDMI

[DRONE7]

Agree with Tim's recommendation.seems your available formats/card specs may not align with surround output....

Perhaps the available formats in hardware do not align..?

Code:

Sample formats: U8, S16_LE

I have not used this (yet) but it may be of some help ?
