From 7099a6a220c33d9c115e19e9f03ac61caa8358b5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Volker=20R=C3=BCmelin?= Date: Fri, 23 Sep 2022 20:36:30 +0200 Subject: [PATCH] audio: fix GUS audio playback with out.mixing-engine=off MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix GUS audio playback with out.mixing-engine=off. The GUS audio device needs to know the amount of samples to produce in advance. To reproduce start qemu with -parallel none -device gus,audiodev=audio0 -audiodev pa,id=audio0,out.mixing-engine=off and start the cartoon.exe demo in a FreeDOS guest. The demo file is available on the download page of the GUSemu32 author.
