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>
2010-01-09oss: issue OSS_GETVERSION ioctl only when neededmalc
Signed-off-by: malc <av1474@comtv.ru>
2010-01-09oss: refactor code around policy settingmalc
This fixes a problem with a previous patch spotted by Juergen Lock, thanks to him again. Signed-off-by: malc <av1474@comtv.ru>
2010-01-08oss: workaround for cases when OSS_GETVERSION is not definedmalc
Thanks to Juergen Lock. Signed-off-by: malc <av1474@comtv.ru>

2009-10-02oss/alsa: Do not invoke UB described in 7.15.1.1malc
Additional argument (whether to try poll mode) is only passed with VOICE_ENABLE command. Thanks to Markus Armbruster for noticing the potential breakage.

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>

2008-06-08Check the returned audio_buf_info fieldsmalc
At least on one system zero is returned in either fragsize or fragstotal (reported by Dave Scott), this results in an audio_calloc failing the audio_bug check and another ominous error message.
