From 69a802792ab3705074585a75f5645297ae9f6794 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 5 Sep 2023 11:41:05 +0200 Subject: [PATCH] audio: remove QEMU_AUDIO_* and -audio-help support These have been deprecated for a long time, and the introduction of -audio in 7.1.0 has cemented the new way of specifying an audio backend's parameters. However, there is still a need for simple configuration of the audio backend in the desktop case; therefore, if no audiodev is passed to audio_init(), go through a bunch of simple Audiodev* structures and pick the first that can be initialized successfully. The only QEMU_AUDIO_* option that is left in, waiting for a better idea, is QEMU_AUDIO_DRV=none which is used by qtest. Remove all the parsing code, including the concept of "can_be_default" audio drivers: now that audio_prio_list[] is only used in a single place, wav can be excluded directly in that function.
