Subject: buffer_bytes not multiple of period_bytes
Date: Wed, 19 Apr 2006 18:54:38 -0700	[thread overview]
Message-ID: <4446E9DE.4080709@kenati.com> (raw)

Hi all,

I just noticed that alsa doesn't allocate a buffer size that is a 
multiple of the period size. For example when aplay plays a 8000 sample 
rate wav file, the driver gets the following:

    buf_bytes=8000
    period_bytes=1024

How am I going to dma the last period ?

I verified that the 16000 sample rate also has the same problem. 
However, when the sample rate is 44100 the buffer size is a perfect 
multiple of the period size.

Thanks,


Carlos Munoz
