I decided to test out MicroMPX on the Raspberry Pi using the HifiBerry and DAC+ Pro (with XLR output). When I send audio from a Windows 7-based processor, it sounds very distorted on the air. The same Windows machine sounds great when using its own internally 192 Khz sound card.
The RDS comes through just fine. The audio sounds like it is being clipped somewhere, although the levels on the output of the Raspberry Pi are where they should be.
Are there command line items to try for the Raspberry Pi version? Any suggestions on tracking down the distortion?
Thanks in advance.
This looks to be a problem with the 9.20 build. I tried version 9.11 of the receiver and all works well.
