* audio: swap audio_rate_get_bytes() function parametersVolker Rümelin2022-10-111-1/+1
| | | | | | | | | | | Swap the rate and info parameters of the audio_rate_get_bytes() function to align the parameter order with the rest of the audio_rate_*() functions.

* audio: restore mixing-engine playback buffer sizeVolker Rümelin2022-03-041-0/+1
| | | | | | | | | | | | | | | | | | | | | Commit ff095e5231 "audio: api for mixeng code free backends" introduced another FIFO for the audio subsystem with exactly the same size as the mixing-engine FIFO. Most audio backends use this generic FIFO. The generic FIFO used together with the mixing-engine FIFO doubles the audio FIFO size, because that's just two independent FIFOs connected together in series. For audio playback this nearly doubles the playback latency. This patch restores the effective mixing-engine playback buffer size to a pre v4.2.0 size by only accepting the amount of samples for the mixing-engine queue which the downstream queue accepts.

* audio: fix bug 1858488Volker Rümelin2020-01-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The combined generic buffer management code and buffer run out code in function audio_generic_put_buffer_out has a problematic behaviour. A few hundred milliseconds after playback starts the mixing buffer and the generic buffer are nearly full and the following pattern can be seen. On first call of audio_pcm_hw_run_out the buffer run code in audio_generic_put_buffer_out writes some data to the audio hardware but the generic buffer will fill faster and is full when audio_pcm_hw_run_out returns. This is because emulated audio devices can produce playback data at a higher rate than the audio backend hardware consumes this data. On next call of audio_pcm_hw_run_out the buffer run code in audio_generic_put_buffer_out writes some data to the audio hardware but no audio data is transferred to the generic buffer because the buffer is already full. Then the pattern repeats. For the emulated audio device this looks like the audio timer period has doubled. This patch splits the combined generic buffer management code and buffer run out code and calls the buffer run out code after buffer management code to break this pattern. The bug report is for the wav audio backend. But the problem is not limited to this backend. All audio backends which use the audio_generic_put_buffer_out function show this problem.

* audio: replace shift in audio_pcm_info with bytes_per_frameKővágó, Zoltán2019-10-181-3/+3
| | | | | | | | | | | The bit shifting trick worked because the number of bytes per frame was always a power-of-two (since QEMU only supports mono, stereo and 8, 16 and 32 bit samples). But if we want to add support for surround sound, this no longer holds true.

| | | | | | | | | | | This commit removes the ad-hoc rate-limiting code from noaudio and wavaudio, and replaces them with a (slightly modified) code from spiceaudio. This way multiple write calls (for example when the circular buffer wraps around) do not cause problems.

* audio: -audiodev command line option basic implementationKővágó, Zoltán2019-03-111-1/+1
| | | | | | | | | | | | | | | | | | | | Audio drivers now get an Audiodev * as config paramters, instead of the global audio_option structs. There is some code in audio/audio_legacy.c that converts the old environment variables to audiodev options (this way backends do not have to worry about legacy options). It also contains a replacement of -audio-help, which prints out the equivalent -audiodev based config of the currently specified environment variables. Note that backends are not updated and still rely on environment variables. Also note that (due to moving try-poll from global to backend specific option) currently ALSA and OSS will always try poll mode, regardless of environment variables or -audiodev options.

| | | | | | | | | | | | | | | | | | This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.
