Some codecs support it in the kernel (e.g. pcm512x).

I'm not sure it really is this simple, but the things I'm using start to work...
I guess this would break if a linear rate plugin is used, since it may overflow. Actually, for other rate plugins in alsa-plugins, they set unlimited (both zero). That said, the defines there are essentially only for the linear rate plugin.
And, looking at the code now, I believe the usage of assert() in snd_spcm_init() is just wrong. Such a condition shouldn't be assert() but let the PCM parameter resolver handling it instead.
thanks,
Takashi
Cheers, Peter
