Subject: What to do when a device clears the buffer in the start trigger?
Date: Wed, 31 Jul 2019 19:48:13 +0200 [thread overview]
Message-ID: <CAKSqxP_po3DRQvhqb-VrwD_NitzSRa0a+28NNA8SajUaZN+qbQ@mail.gmail.com> (raw)
Hello,
I have a device which clears the DMA buffer when I command it to start the
playback. How can this be workarounded?
I found the SNDRV_PCM_INFO_DOUBLE flag, but it doesn't seem that it changes
alsa/alsa-lib behaviour. I wasn't able to find any drivers which shared
this quirk.
I'd like to avoid double buffering if possible, as once the stream is
actually started it's not required.
Thank you,
Paul Pawlowski
