Hi,
With alsa-lib and alsa-utils cross-compiled for ARM by buildroot (currently version 1.0.19, but earlier versions seem to be equally affected), I encounter the effect that snd_pcm_hw_params_get_period_size() does not write the expected value to the given snd_pcm_uframes_t pointer. In fact, this variable is not written at all. This makes aplay calculate 0 for chunk_bytes in set_params() and then exit with the bogus error message "Not enough memory". I did some tracing and found out that the function called for snd_pcm_hw_params_get_period_size() is in fact __old_snd_pcm_hw_params_get_period_size() which has a different footprint and hence the pointer given to it is leaved untouched.
As I don't fully understand all the system behind the symbol names remapping, I'm stuck here. Can anybody reproduce this bug?
