From: bones_was_here Date: Sun, 25 Aug 2024 02:43:30 +0000 (+1000) Subject: snd_mutewhenidle: add only-when-minimised mode, fix cl_capturevideo compat, cleanup X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=58de196cfa843ad052291cd35be3ebd29e57efcc;p=xonotic%2Fdarkplaces.git snd_mutewhenidle: add only-when-minimised mode, fix cl_capturevideo compat, cleanup Maybe snd_mutewhenidle 2 should be the default? When inactive/minimised with snd_mutewhenidle enabled, the audio capture was unreliable and sound was sometimes output when it should have been muted. Closes https://gitlab.com/xonotic/darkplaces/-/issues/92 (the video issue was already fixed). Timedemos now share the same mute implementation as snd_mutewhenidle.
