docs: fix references to docs/devel/tracing.rst Commit e50caf4a5c ("tracing: convert documentation to rST") converted docs/devel/tracing.txt to docs/devel/tracing.rst. We still have several references to the old file, so let's fix them with the following command: sed -i s/tracing.txt/tracing.rst/ $(git grep -l docs/devel/tracing.txt) Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20210517151702.109066-2-sgarzare@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

audio: add Apple Sound Chip (ASC) emulation The Apple Sound Chip was primarily used by the Macintosh II to generate sound in hardware which was previously handled by the toolbox ROM with software interrupts. Implement both the standard ASC and also the enhanced ASC (EASC) functionality which is used in the Quadra 800. Note that whilst real ASC hardware uses AUDIO_FORMAT_S8, this implementation uses AUDIO_FORMAT_U8 instead because AUDIO_FORMAT_S8 is rarely used and not supported by some audio backends like PulseAudio and DirectSound when played directly with -audiodev out.mixing-engine=off.
