Since I'm the owner of a Supercharger for a few weeks, I took the opportunity to add a feature that I'm missing to the makewav tool, used for creating the audio output: direct soundcard support.
You can now run:
to get a list of available sound devices, that looks like that on my linux machine:
device #0: HDA Intel PCH: ALC892 Analog (hw:0,0) device #1: HDA Intel PCH: ALC892 Digital (hw:0,1) device #2: HDA Intel PCH: ALC892 Analog (hw:0,2) device #3: HDA Intel PCH: HDMI 0 (hw:0,3) device #4: HDA Intel PCH: HDMI 1 (hw:0,7) device #5: USB PnP Sound Device: USB Audio (hw:1,0) device #6: sysdefault device #7: front device #8: surround40 device #9: surround41 device #10: surround50 device #11: surround51 device #12: surround71 device #13: iec958 device #14: spdif device #15: hdmi device #16: pulse device #17: dmix device #18: default
To upload data directly to the sound card, there's the "-a" option.
makewav -a cart.bin
which will output the audio to the default device.
makewav -a"USB PnP Sound Device: USB Audio (hw:1,0)" cart.bin
Will output the audio to my USB sound card which is attached to the Supercharger.
Since I'm lazy at typing, you can *append* a star at the end of the name for substring match, so in my case it's
makewav -aUSB* cart.bin
If there are more than one matching, the first match of the list will be used.
I'm also lazy at coding, so that's why the star only works at the end of the device name.
If switching to Supercharger mode via "-ts" also the default speed for audio creation will be changed from 1 to 0, because 1 didn't work with my Supercharger.
