Hi, I have made some sort of progress. When trying to play I wav file (which should be saying "side right") I can get it to say "side" and then loop over that instead of just looping over "si si si si si", this by modifying the period/buffer time/size. But it'll still loop over the sound again and again. If I issue the flag --test-position it will sometimes play the entire wav file, looping first over "side" a few times and then over "right". But it'll give me xrun errors with quite ridiculous time out errors (several million ms). I also get write errors every now and again (line 1442 in aplay.c) regardless of what flags I give to aplay. I'm guessing it's some problem with the driver writing to the sound card, could it be timing errors or perhaps some problems with the fact that the machine is running in big endian mode?
