2022-05-14introduce -audio as a replacement for -soundhwPaolo Bonzini2-1/+8
-audio is used like "-audio pa,model=sb16". It is almost as simple as -soundhw, but it reuses the -audiodev parsing machinery and attaches an audiodev to the newly-created device. The main 'feature' is that it knows about adding the codec device for model=intel-hda, and adding the audiodev to the codec device. In the future, it could be extended to support default models or builtin devices, just like -nic, or even a default backend. For now, keep it simple.

2022-04-06Replace config-time define HOST_WORDS_BIGENDIANMarc-André Lureau2-2/+2
Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

2022-03-04audio: restore mixing-engine playback buffer sizeVolker Rümelin9-18/+80
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.

2022-03-04jackaudio: use more jack audio buffersVolker Rümelin1-2/+2
The next patch reduces the effective qemu playback buffer size by timer-period. Increase the number of jack audio buffers by one to preserve the total effective buffer size. The size of one jack audio buffer is 512 samples. With audio defaults that's 512 samples / 44100 samples/s = 11.6 ms and only slightly larger than the timer-period of 10 ms. The larger jack audio buffer increases audio dropout safety, because the high priority jack-audio worker threads can provide audio data for a longer period of time as with a smaller buffer and more audio data in the mixing engine buffer that they can't access.

2021-06-23coreaudio: Lock only the bufferAkihiko Odaki1-61/+41
On macOS 11.3.1, Core Audio calls AudioDeviceIOProc after calling an internal function named HALB_Mutex::Lock(), which locks a mutex in HALB_IOThread::Entry(void*). HALB_Mutex::Lock() is also called in AudioObjectGetPropertyData, which is called by coreaudio driver. Therefore, a deadlock will occur if coreaudio driver calls AudioObjectGetPropertyData while holding a lock for a mutex and tries to lock the same mutex in AudioDeviceIOProc. audioDeviceIOProc, which implements AudioDeviceIOProc in coreaudio driver, requires an exclusive access for the device configuration and the buffer. Fortunately, a mutex is necessary only for the buffer in audioDeviceIOProc because a change for the device configuration occurs only before setting up AudioDeviceIOProc or after stopping the playback with AudioDeviceStop. With this change, the mutex owned by the driver will only be used for the buffer, and the device configuration change will be protected with the implicit iothread mutex.

Before commit 7d6948cd98cf5ad8a3458a4ce7fdbcb79bcd1212, it was coded to retrieve the initial output stream format settings, modify the frame rate, and set again. However, I removed a frame rate modification code by mistake in the commit. It also assumes the initial output stream format is consistent with what QEMU expects, but that expectation is not in the code, which makes it harder to understand and will lead to breakage if the initial settings change. This change explicitly sets all of the output stream settings to solve these problems.

2021-06-17paaudio: remove unused stream flagsVolker Rümelin1-4/+1
In current code there are no calls to pa_stream_get_latency() or pa_stream_get_time() to receive latency or time information. Remove the flags PA_STREAM_INTERPOLATE_TIMING and PA_STREAM_AUTO_TIMING_UPDATE which instruct PulseAudio to calculate this information in regular intervals.
