I have two Max2Play units. The first is an older RP2 with a Wolfson audio card running M2P with Squeezeplug. The new unit is a RP3 with a Hifiberry Amp+ running standard M2P with hifiberry. For some reason this newer unit will not play specific audio streams. The only difference I have found is 64kbps CBR, AAC Radio vs. 48kbps CBR, AAC Radio. The newer unit will not play the 48kbps CBR, AAC Radio streams. Any ideas?
