Consider snd_pcm_writei(), most of the time is usually spent blocked waiting for a period to elapse. It is perfectly ok to call snd_pcm_delay() during this time. But if one isn't allowed to make any other pcm calls during snd_pcm_writei() then this can't be done.

Then use non-blocking mode. Blocking mode is suitable only for applications that do not want to access the device while waiting.
