In the process of installing Linux on a blue and white FireWire iBook we had here at work, I decided I wanted to play an audio CD on it. Great idea, right? Wrong. I discovered that Red Book CD audio doesn't work. Ok, so I installed the cdfs module, mount the CD as type cdfs, and play it. Garbled audio, it was pretty bad. I did, however, discover that the appropriate command line to sox would convert the samples from signed to unsigned - and then the audio played perfectly. (Using /dev/dsp in the process, but no big deal at this point.)
I did write a Perl script that opens /dev/dsp and queries for supported sample formats from the driver - the driver says it only supports signed 16-bit big- and little-endian samples. Hm. Who is the developer for the dmasound_awacs/dmasound_pmac driver, then? What can be done about this DACA weirdness? Also, will there ever be a software volume control for it, other than the keys on the keyboard (which don't seem to affect the volume from external speakers)?
