[Pkg-alsa-devel] Bug#541786: vdownmix: Update documentation with totem-gstreamer setup intructions

[Apelete Seketeli]

Package: libasound2-plugins
Version: 1.0.20-1
Severity: wishlist

Hi,

I'm using totem-gstreamer on a laptop, and lately I've been trying to play surround videos through stereo speakers without success.
I heard of vdownmix and tried to use it, but the info given in the vdownmix.txt file didn't help. I think it's important to let users know how to use this plugin with totem-gstreamer since it's the default video player for Gnome. I noticed while googling the problem that many people are failing to play surround sound in Totem (I couldn't find any help searching on the web, not even in the Alsa Wiki), and some of them resort to PulseAudio for that.
I have finally succeeded in setting this up, and I thought I'll give you the setup so you can update the documentation, making it available for other people to use. So here is the alternative I found to use vdownmix in totem (should work with any other player too) without PulseAudio:

pcm.!downmix51 {
 type vdownmix
 slave.pcm "surround51"
}

pcm.!default "plug:downmix51"


I don't kown if the example given in vdownmix.txt is really false, but the fact is it didn't work on my HDA Intel enabled laptop (Thinkpad X60 btw).
Hope this help.
