My setup looks like this: Guitar goes to Line6 Helix, amp and cab sim there, output goes to AV receiver via either analog or digital input.
The problem is, when the simulated amp is really loud, helix global volume is loud, and/or I hit the string hard, especially the initial attack, I hear crackling sound from the speaker connected to receiver, although the sound volume is not that high at all.
When I reduce the volume on Helix and increase it on the receiver, it seems to remedy the problem. But, if possible I'd like not to change the receiver volume, because other sources such as PC via optical cable, HDMI ARC and so on are more or less matched to the desired final volume level.
So, my question is - I assume the cracking I hear means the source volume is too high. Can I do something about it, except for obvious things like playing quieter, preferrably without increasing volume on receiver?
