The only thing I personally had an actual issue with is using "front" for stereo rather than "default". I don't seem able to come up with a compelling reason why it should be "front" myself, so one tweak could perhaps be to only change the stereo device back to "default"?
Because then you can't guarantee or even discover what the playback rate and bitdepth are. There's no way to ensure bit-exact playback in a plug device, where 'front' is usually a non-plug alias.
The SND_PCM_NO_AUTO_* flags are there for exactly this reason: http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m.html#ga64fa40b5 56374dabe40d4874242fee19
Where would those flags be used, and how is that different from calling
snd_pcm_hw_params_set_rate_resample()
(with '0' to disable) on the pcm/configuration space?
