CVS commit: src/sys/dev
Module Name: src
Committed By: nat
Date: Tue May 15 00:28:00 UTC 2018
Expose the audio_info structure of vchan zero(0) the mix ring to allow
setting the hardware gain and balance via audioctl(1) using the -p 0
It is not possible to influence the hardware gain/blance from the
audio_info structure of vchans 1 onwards. It is now possible to return
the audio mixers audio format from the audio_info structure of vchan 0 to
ease applications configuring for mmapped play back.
This is conformant to the audio specification posted on tech-kern see:
"NetBSD Audio Specification 2018"
or audio.7 manual page to be added in a follow up commit.
