Subject: DSD: Playing silence before and after actual audio data
Date: Thu, 15 Oct 2015 15:01:56 +0200	[thread overview]
Message-ID: <561FA3C4.8040205@streamunlimited.com> (raw)

Hi guys,

I'm trying to figure out the best way to insert ~40ms worth of silence 
pattern before and after playing back DSD data.

There seems to be support inside ALSA for a DSD silence pattern, but as 
far as I have seen it's only used when an underrun might occur 
(silence_threshold, silence_size).

Is there some possibility inside ALSA to basically insert silence before 
and after playback, or how hard would it be to implement something like 
this? I have looked a bit for myself and for me it seems that the 
modifications needed inside ALSA to achieve this feature are 
substantial, but of course I also might have missed something.

Martin
