Iriver H10 5g
Fresh pull and the 090218 patch.
With Speed turned on.
Crossfeed - can't get it lock up. Seems to work fine.
With Bass, Treble, Eq on.
I can change the settings while a song is playing and everything is fine.
If I skip to the next song, ffw, or try playing a new song with the
setting already on, lock up.
