My HTPC worked fine until I try to fix the few seconds silence at the start of every PCM sound in XBMC menu, mp3, etc.

I edited /etc/asound.conf like that :

Code:

pcm.!default {
   type plug
   slave {
       pcm "hw:0,3"
       rate 48000
   }
}

and created ~/.asoundrc but I don't remember exactly what I did and it doesn't fix the initial problem.

The result: now I have no sound in PCM (Dolby Digital and DTS still work).

Configuration :
MB: Gigabyte GA-880GM-UD2H
GPU: Asus EN210 SILENT (HDMI)
Receiver : Onkyo TX-SR608
Audio Output Device "HDA NVidia hdmi" (no change here)
Passthrough Output Device "HDA NVidia hdmi" (no change here)

Can you send me the default asound.conf file ?

Thanks

Up… anyone ??

It's strange, I can hear the sound, but at a very low level (volume at 80/100 on my receiver).

Are you sure it's not just the volume levels in Ubuntu? If you enter the command "alsamixer" (without the quotes) on the command line you can see what the output levels are for each channel. I believe there is also an add-on available so you can check the volume levels from within XBMC.

Probably alsamixer as Devaron mentioned.

BTW you don't need rate in your asound.conf since you have type plug which does the same thing.

Thanks I'll try this evening

PCM level seems ok :

Now I can hear navigation sounds at a normal level with :

~/.asoundrc

Code:

pcm.!default {
type hw
card 1
device 3
}

But still no mp3/divx sound

A fresh XBMC install has asound.conf and .asoundrc files ?

I remember when I installed XBMC, I don't edit theses files, I only set the XBMC audio settings with Nvidia HDA HDMI and it worked out of the box…

For info :

aplay -l

Code:

IT WORKS

The solution was in this thread.

The volume was set to -50dB, I don't know why.
