Yeah, I'd really like to get the beeps back too. My Rio seems rather reluctant to take commands from the remote sometimes. It would be good to get confirmation that it was accepting my commands. I really don't know how to go about exploring the reasons behind the missing beeps and don't have a clue about what Hugo mentioned below:

You could try these (empeg_mixer.c):
2x10 band eq mode - write Y_OutSwi = 0xa49 (currently 0xa7c)
4x5 band eq mode - write Y_OutSwi = 0xa50 (currently 0xa85) - this *may* disable the onboard DAC though.
Once I get the boards on the market, perhaps someone else can tackle this issue.
