Hmmh. Not sure if that helps. I'd guess that as soon as you call amixer/alsamixer, you'll find the same useless stuff in asound.state. I do know that a hell lot of firmware doesn't really initializes properly towards Alsa. Most drivers/firmware are crap in this regard. I did sent a HifiBerry DAC back the other day, because of a crappy driver. It's ridiculous that many designers seem to be happy as longs as plain 16/44.1 makes it to the output. I'd check with the guy who's in charge for the Wandboard driver to get things properly initialized. ::: ' Touch Toolbox and more' (http://soundcheck-audio.blogspot.com) ::: by soundcheck ------------------------------------------------------------------------ soundcheck's Profile: http://forums.slimdevices.com/member.php?userid=34383 View this thread: http://forums.slimdevices.com/showthread.php?t=101624 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
