No, I don't think it is. I get similar problems with my emi 2|6 and alsaplayer, mplayer, xmms, ...
My impression is that ALSA assumes that the connected interfaces _always_ allow for the same Endianess as the system. This, of course, isn't always so. Mplayer: Checking audio filter chain for 44100Hz/2ch/16bit -> 44100Hz/2ch/16bit... AF_pre: af format: 2 bps, 2 ch, 44100 hz, big endian signed int AF_pre: 44100Hz 2ch Signed 16-bit (Big-Endian) alsa-init: requested format: 44100 Hz, 2 channels, Signed 16-bit (Big-Endian) alsa-init: soundcard set to emi alsa-init: format Signed 16-bit (Big-Endian) are not supported by hardware, trying default alsa9: 44100 Hz/2 channels/4 bpf/65536 bytes buffer/Signed 16 bit Little Endian AO: [alsa9] 44100Hz 2ch Signed 16-bit (Little-Endian) (2 bps) alsaplayer either dies with "FIXME: f_unsynchronization is set.Please contact alsaplayer team." or produces static noise. aplay does get this right, so it seems to use a different method of querying the device.
