* alsa: disable timer-based scheduling inside a VMLennart Poettering2009-11-051-0/+2
| | | | | | | | | | | | | | | 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 Poettering2009-09-091-5/+5
| | | | | | | | | | | | | - 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.

* alsa: rework mixer logicLennart Poettering2009-06-171-63/+53
| | | | | | | | | | | | 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.

* alsa: allow configuration of fallback device strings in profilesLennart Poettering2009-04-291-0/+1
| | | | | | 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.

| | | | | This allows us to easily use different mixer controls for analog and spdif output.

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
