Reply To: AMP2 error: "Usage: amixer [command]"

Does anyone have an idea to set up 2x RP with 2x multisqueeze?
The curious thing is if I have RP2 on multisqueeze (with 2 players) and RP1 with just one audioplayer (without multisqueeze) than it works.
With the above mentioned set up the RP1 get´s the mac dc:a6:32:12:f4:41 and is listed in the LMS.

But soon as I switch back to multi for the RP1 too, the LMS is switching between these both mac address.
I also tried to flash both RP´s new, without success.
