I need to convenience switch the audio sink ( USB DAC ) between pulseaudio and a high-res proprietary music render that uses direct ALSA card access. Some background; two applications - a Bluetooth AD2P streamer ( hence pulseaudio ) and a network based HiRes Audio streamer. Both can be "connected" at the same time but only one will render audio. Pressing play on one, pauses the other and takes the sound sink and visa-vera. I have this all working but when switching from the proprietary network application to bluetooth the change over takes 5 seconds+.
Example: 1) music is being streamed via Bluetooth ( bluez5.48)/pulse audio 9.0 2) User decides he wants to listen to a DSD or something. Press play on his tablet etc. 3) The embedded Hi-res application gets notified of a play request and starts to teardown the Bluetooth side 4) Bluetooth incoming gets paused and pasuspender grabs the audio sink 5) Hi-res app detects the sink is free, bolts up and starts to stream the users DSD.
As mentioned it all works. However pasuspender takes almost 5 seconds to secure/free the audio sink; thi sis just too long. Any ideas.
To summarise, I need a quick and reliable way to take ownership of a pulseaudio sink need by an indepedant application.
Thanks.
