* alsa: correct assumptions about channels an element lacksVladimir Kokarev2009-09-171-10/+2
| | | | | | | If an element does not control some channels assume they are 0dB in comparison to the other elements, i.e. do not influence the volume at all. Previously we were assuming they were as high as the highest of the channels we do control.

* alsa: rework buffer/period configurationLennart Poettering2009-09-094-130/+217
| | | | | | | | | | | | | - 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-sink: reduce the amount of smoother updatesWim Taymans2009-08-201-4/+22
| | | | | | | | | | | | | | Exponentially increase the amount of time between smoother updates. We start with a 2ms interval and increase up to 200ms intervals. Smoother updates and the resulting linear regression take a fair amount of CPU so we want to reduce the amount of updates.

* sink: volume handling rework, new flat volume logicLennart Poettering2009-08-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | - We now implement a logic where the sink maintains two distinct volumes: the 'reference' volume which is shown to the users, and the 'real' volume, which is configured to the hardware. The latter is configured to the max of all streams. Volume changes on sinks are propagated back to the streams proportional to the reference volume change. Volume changes on sink inputs are forwarded to the sink by 'pushing' the volume if necessary. This renames the old 'virtual_volume' to 'real_volume'. The 'reference_volume' is now the one exposed to users. By this logic the sink volume visible to the user, will always be the "upper" boundary for everything that is played. Saved/restored stream volumes are measured relative to this boundary, the factor here is always < 1.0. - introduce accuracy for sink volumes, similar to the accuracy we already have for source volumes. - other cleanups.

* source: rework volume handlingLennart Poettering2009-08-191-13/+24
| | | | | | | | | | | | | - drop the 'virtual_' prefix from s->virtual_volume since we don't distuingish between reference and real volumes for sources - introduce an accuracy for source volumes: if the hardware can control the volume "close enough" don't necessarily adjust the rest in software unless it is beyond a certain threshold. This should save a little bit of CPU at the expensive of a bit of accuracy in volume handling. - other minor cleanups

* Recover stream when it's suspended upon rewindLubomir Rintel2009-08-031-1/+7
| | | | | | | | | | | | | Error from snd_pcm_rewind() might mean we just woke up from suspend and didn't have a chance to try to recover the stream since we didn't write to it in between. Call try_recover() in such cases. Note that for this to work kernel must return ESTRPIPE instead of EBADF for rewind/forward attempts on suspended streams, so that snd_pcm_recover() can recognize it should snd_pcm_resume() the stream. This is not the case yet (2.6.31-rc5), patch is available. Signed-off-by: Lubomir Rintel <lkundrak@v3.sk>
* 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.
