From 4db3e634c77a671fadbba6d4d39e0d21232e5609 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Volker=20R=C3=BCmelin?= Date: Sat, 4 Jan 2020 10:11:20 +0100 Subject: paaudio: drop recording stream in qpa_fini_in MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Every call to pa_stream_peek which returns a data length > 0 should have a corresponding pa_stream_drop. A call to qpa_read does not necessarily call pa_stream_drop immediately after a call to pa_stream_peek. Test in qpa_fini_in if a last pa_stream_drop is needed. This prevents following messages in the libvirt log file after a recording stream gets closed and a new one opened. pulseaudio: pa_stream_drop failed pulseaudio: Reason: Bad state pulseaudio: pa_stream_drop failed pulseaudio: Reason: Bad state To reproduce start qemu with -audiodev pa,id=audio0,in.mixing-engine=off and in the guest start and stop Audacity several times.
