Details

Description:
After ALSA upgrade from 1.0.28-1 to 1.0.29-1, sound output is about half a second delayed.
Downgrading alsa-lib, alsa-plugins and alsa-utils to 1.0.28 resolved it for me.
Haven't tested yet if sound is delayed without pulseaudio installed.

Additional info:
* alsa-lib 1.0.29-1, alsa-utils 1.0.29-1, alsa-plugins 1.0.29-1, pulseaudio 6.0-1
* default.pa: http://pastebin.com/qBQpAFfb

Steps to reproduce:
Upgrade ALSA from 1.0.28-1 to 1.0.29-1, reboot system, play audio/video.
This task depends upon

Please report it upstream maillist with additional information:
- what PCM do you have (aplay -l)?
- how do you try to play audio (aplay?)

Commenting out lines 47-49 in my default.pa (http://pastebin.com/qBQpAFfb) and uncommenting lines 56-61, thus re-enabling autodetect instead of using dmix like before, fixed my problem.
