Hi, the people of HifiBerry told me (see linked thread) that there is no "THE driver" and therefore I can not provide its source code. What I know that speaker-test -t wav -c 2 and mplayer -ao alsa:device=hw=1.0 /usr/share/sounds/alsa/Front_Right.wav work but aplay -D hw:1,0 /usr/share/sounds/alsa/Front_Right.wav and aplay -D plughw:1,0 /usr/share/sounds/alsa/Front_Right.wav don't. So for me it looks like there is something wrong with aplay. Because if there would be a fundamental problem with the driver, how could the other two programs (speaker-test is even bundled with aplay so I assume they don't do some crazy stuff) work? As aplay is used as default player in many places (e.g. in the text-to-speach-program I'm using) I would really appreciate if aplay would work too. I'm not an expert, therefor I can't check the code my self but if there is anything I can test to help to fix it, just let me know.
