2013-11-07ossaudio: check for oss support in oss_audio_initGerd Hoffmann
Check whenever the device path (/dev/dsp by default) exists and qemu is allowed to access it. Return NULL if it isn't, so ossaudio will not be used on systems wihtout oss support (increasinly common on modern linux systems). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-11-07Revert "ossaudio: do not enable by default"Gerd Hoffmann
This reverts commit c905c5012ac0c6fde3b8094d2206a3139deddba2. There is a better fix for the issue at hand. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-11-05ossaudio: do not enable by defaultAnthony Liguori
Modern Linux's no longer support /dev/dsp so enabling it by default causes audio failures on newer Linux distros. Signed-off-by: Anthony Liguori <aliguori@amazon.com> Tested-by: Andreas Färber <afaerber@suse.de> Message-id: 1383497154-9271-1-git-send-email-aliguori@amazon.com

2012-12-19janitor: do not include qemu-char everywherePaolo Bonzini
Touching char/char.h basically causes the whole of QEMU to be rebuilt. Avoid this, it is usually unnecessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2012-12-19janitor: do not rely on indirect inclusions of or from qemu-char.hPaolo Bonzini
Various header files rely on qemu-char.h including qemu-config.h or main-loop.h, but they really do not need qemu-char.h at all (particularly interesting is the case of the block layer!). Clean this up, and also add missing inclusions of qemu-char.h itself. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2011-01-12audio: split sample conversion and volume mixingMichael Walle
Refactor the volume mixing, so it can be reused for capturing devices. Additionally, it removes superfluous multiplications with the nominal volume within the hardware voice code path. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: malc <av1474@comtv.ru>

2010-01-13Workaround for broken OSS_GETVERSION on FreeBSD, part twoJuergen Lock
Turns out on those versions of FreeBSD (>= 7.x) that know OSS_GETVERSION the ioctl doesn't actually work yet (except in the Linuxolator), so if building on FreeBSD assume the sound drivers are new enough if the ioctl returns the errno it does currently on FreeBSD. (Rev 2 after private discussion with malc.) Signed-off-by: Juergen Lock <nox@jelal.kn-bremen.de> Signed-off-by: malc <av1474@comtv.ru>
2010-01-09oss: fix fragment settingmalc
Previous patch introduced subtle regression, in cases when OSS_GETVERSION fails the code wasn't falling back to SNDCTL_DSP_SETFRAGMENT. Signed-off-by: malc <av1474@comtv.ru>

2009-09-18audio: internal API changemalc
pcm_ops.run_out now takes number of live samples (which will be always greater than zero) as a second argument, every driver was calling audio_pcm_hw_get_live_out anyway with exception of fmod which used audio_pcm_hw_get_live_out2 for no good reason. Signed-off-by: malc <av1474@comtv.ru>
