2021-01-15dsoundaudio: rename dsound_open()Volker Rümelin
Rename dsound_open() to dsound_set_cooperative_level(). The only task of that function is to set the cooperative level for DirectSound.

2021-01-15dsoundaudio: replace GetForegroundWindow()Volker Rümelin
GetForegroundWindow() doesn't necessarily return the own window handle. It just returns a handle to the currently active window and can even return NULL. At the time dsound_open() gets called the active window is most likely the shell window and not the QEMU window. Replace GetForegroundWindow() with GetDesktopWindow() which always returns a valid window handle, and at the same time replace the DirectSound buffer flag DSBCAPS_STICKYFOCUS with DSBCAPS_GLOBALFOCUS where Windows only expects a valid window handle for DirectSound function SetCooperativeLevel(). The Microsoft online docs for IDirectSound::SetCooperativeLevel recommend this in the remarks. This fixes a bug where you can't hear sound from the guest. To reproduce start qemu with -machine pcspk-audiodev=audio0 -device intel-hda -device hda-duplex,audiodev=audio0 -audiodev dsound,id=audio0,out.mixing-engine=off from a shell and start audio playback with the hda device in the guest. The guest will be silent. To hear guest audio you have to activate the shell window once.

2020-04-06dsoundaudio: dsound_get_buffer_in should honor *sizeVolker Rümelin
This patch prevents an underflow of variable samples in function audio_pcm_hw_run_in(). See commit 599eac4e5a "audio: audio_generic_get_buffer_in should honor *size". This time the while loop in audio_pcm_hw_run_in() will terminate nevertheless, because it seems the recording stream in Windows is always rate limited.

2020-04-06dsoundaudio: fix "Could not lock capture buffer" warningVolker Rümelin
IDirectSoundCaptureBuffer_Lock() fails on Windows when called with len = 0. Return early from dsound_get_buffer_in() in this case. To reproduce the warning start a linux guest. In the guest start Audacity and you will see a lot of "Could not lock capture buffer" warnings.

2020-04-06dsoundaudio: fix never-ending playback loopVolker Rümelin
Currently the DirectSound backend fails to stop audio playback in dsound_enable_out(). To detect a lost buffer condition dsound_get_status_out() incorrectly uses the error code DSERR_BUFFERLOST instead of flag DSBSTATUS_BUFFERLOST as a mask and returns with an error. As a result dsound_enable_out() returns early and doesn't stop playback. To reproduce the bug start qemu on a Windows host with -soundhw pcspk -audiodev dsound,id=audio0. On the guest FreeDOS 1.2 command line enter beep. The image Day 1 - F-Bird from the QEMU Advent Calendar 2018 shows the bug as well.

2019-10-18audio: replace shift in audio_pcm_info with bytes_per_frameKővágó, Zoltán
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.

2019-03-11audio: -audiodev command line option basic implementationKővágó, Zoltán
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.

2018-02-06audio: Replace AUDIO_FUNC with __func__Alistair Francis
Apparently we don't use __MSC_VER as a compiler anymore and we always require a C99 compiler (which means we always have __func__) so we don't need a special AUDIO_FUNC macro. We can just replace AUDIO_FUNC with __func__ instead. Checkpatch failures were manually fixed.

2015-06-15dsoundaudio: remove primary bufferKővágó, Zoltán
Enabling this option just creates a playback buffer with the specified settings, and then ignores it. It's probably some outdated hack to set audio formats on windows. (The first created stream dictates all other streams settings, at least on some Windows versions). Setting DAC_FIXED_SETTINGS should have the same effect as setting (the now removed) primary buffer.

2015-06-15dsoundaudio: remove *_retries kludgesKővágó, Zoltán
According to MSDN this may happen when the window is not in the foreground, but the default is 1 since a long time (which means no retries), so it should be ok. I've found no problems during testing it on Windows 7 and wine, so this was probably only the case with some old Windows versions.
