Details

You'll need a file in the
root directory called "rover.raw" that's 4 MB and stereo 16-bit raw
PCM. It'll loop that file.

Note also that it's a bootloader build that does all this..

you also need the TI toolchain

Yeah, so this is how I got real sound out of my m:robe for the first time. It's painfully primitive, but at least we know it's possible ;)

This the same patch adjusted to the ZVM and the m:Robe 500.
It doesn't work yet on the ZVM though.
Could a m:Robe 500-owner or Catalin/jdgordon test if this breaks m:Robe 500 compatibility?

Could be, here's a fresh version.

Should apply cleanly to a clean SVN tree.

I committed some part of this into SVN yesterday..
Comment by Karl Kurbjun (kkurbjun) - Thursday, 26 February 2009, 22:01 GMT
I committed the rest of the code to SVN today and it is now working with some minor modifications. To test it I created a test.raw file with audacity per Cat's suggestion (PCM, 16 bits signed, RAW header) and placed it in the root directory. The test can be run by going into debug_ports in the debug menu. This will start playing audio. I modified the dsp build process to be independent of the rockbox build since we will not be able to integrate the DSP compiler. TI only releases Linux binaries for the compilation tools. I am closing this ticket since it is working in SVN.
