[alsa-devel] issue at 44.1 Khz capturing

I see that the buffer allocated is 22050 bytes (and not 22052 bytes). Yes the hardware supports buffers which are not multiple of period size.
Can I forcefully set my buffer size to 22052 bytes and allocate using snd_pcm_lib_malloc_pages and try? Will that help?
