Delay before audio level changes take effect
In Slackware 14 I'm noticing a perceptible delay between the time the audio volume level is changed and when it takes effect. For example, if I use the mouse scroll wheel to change the volume in Amarok there is a half-second delay and then the audio level jumps to the new setting. I've also noticed that muting a video in SMplayer has a similar but more pronounced effect; there is a delay of up to two seconds before the volume is muted. Changing the volume level via Alsamixer does not cause a delay (that I can perceive). I had been using Slack 13.37 prior to installing Slack 14 fresh and I never noticed this before. Does anyone know a way to address this?

I have this happening with 14.0 and mplayer.

Same here with VLC. When I haven't changed the output module and it was set to default the lag was almost intolerable. Sometimes it froze the video and audio just kept playing. It took about five seconds to change the volume.
Then I tried to change the output module to ALSA audio output and the delay is now tolerable. Not immediate but almost. I'm using Nvidia HDMI audio and dmix ALSA plugin. |
Audio and video playbacks use a buffer so anything read before the change, i.e anything in the current buffer, would not be affected.

That figures. It's not that bad, by the way. I totally don't mind it and will probably do nothing to fix it.

I think I found a solution.
Well for me VLC audio delay was tolerable but when I tried out Google Play Music service, the audio was stuttering so badly that I couldn't even think of using it. So I dug a little deeper to find a solution. As I said earlier I'm using Nvidia HDMI audio and ALSA dmix plugin. My asound.conf file looks like this: Code:
