* alsa: remove redundant call to snd_pcm_nonblock()Pierre-Louis Bossart2010-11-171-2/+0
| | | | | | | The PCM handle is already opened with the SND_PCM_NONBLOCK flag. This additional call is useless. Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@intel.com>
* alsa: work around slightly broken _delay implementationsWim Taymans2010-09-141-3/+43
| | | | | | Use snd_pcm_avail_delay() in pa_alsa_safe_delay() so that we can check the delay value against the avail value and patch it up when it looks invalid. Only do this for capture.

* alsa: disable timer-based scheduling inside a VMLennart Poettering2009-11-111-0/+24
| | | | | | | | | | | | | | | In virtual machines sound card clocks and OS scheduling tend to become unreliable, adding various 'uneven' latencies. The adaptive algorithm that handles drop-outs does not handle it this well: in contrast to drop-outs on real machines that are evenly distributed, small and can easily be encountered via the adpative algorithms, drop-outs in VMs tend to happen abruptly, and massively, which is not easy to counter. This patch simply disables timer based scheduling in VMs reverting to classic IO based scheduling. This should help make PA perform better in VMs. https://bugzilla.redhat.com/show_bug.cgi?id=532775

* alsa: rework buffer/period configurationLennart Poettering2009-09-091-84/+164
| | | | | | | | | | | | | - As discussed on alsa-devel it's probably better to initialize the buffer size first, followed by the period size. If that fails try the other way round. If that fails try to configure only buffer size. If that fails try to configure only period size. Finally, try to configure neither. - Don't require integral periods anymore. Both of these changes should help improving compatibility with various weirder sound devices, such as TV cards.
* llvm-clang-analyzer: drop a few unnecessary assignments and other trivial fixesLennart Poettering2009-09-081-1/+1

* alsa: revert to first set number of periods, then set buffer sizeLennart Poettering2009-07-311-26/+29
| | | | | | | Apparently some ALSA drivers aren't happy with getting the buffer size configured first followed the period size. So swap the order again and document this for future reference so that we don't turn that around again.

* alsa: rework mixer logicLennart Poettering2009-06-171-896/+140
| | | | | | | | | | | | Completely rework mixer logic. This now allows controlling a full set of elements from a single sink's volume slider/mute button. This also introduces sink and source "ports" that can be used to choose different input or output ports with the UI. (i.e. "mic"/"line-in" or "speaker"/"headphones". The mixer paths and device maps are now configered in external configuration files and can be tweaked as necessary.

| | | | | | This has the benefit that we can properly support ALSA devices where only the raw 'hw' device exists but no 'front' although it's a proper 2ch stereo device.

Could you please update it for current git? > Great. An updated patch is attached. For symmetry, I added this option to the alsa source module as well. The Ubuntu folks have customized pulse so much that it is difficult for me to get this version working on my system. For this patch I have only made sure that it compiles. But it does pretty much the same thing as the one for 0.9.14, which is working great for me. Thanks, Kyle
