Subject: [PULL 14/30] paaudio: wait for PA_STREAM_READY in qpa_write()
Date: Fri, 15 Jan 2021 14:21:30 +0100 [thread overview]
Message-ID: <20210115132146.1443592-15-kraxel@redhat.com> (raw)
In-Reply-To: <20210115132146.1443592-1-kraxel@redhat.com>
From: Volker Rümelin <vr_qemu@t-online.de>
Don't call pa_stream_writable_size() in qpa_write() before the
playback stream is ready. This prevents a lot of the following
pulseaudio error messages.
pulseaudio: pa_stream_writable_size failed
pulseaudio: Reason: Bad state
To reproduce start qemu with
-parallel none -device gus,audiodev=audio0
-audiodev pa,id=audio0,out.mixing-engine=off
