Hi there.

I am new to this and i am experiencing some problems.
I installed latest minimal Ubuntu 11.04 64 Bit on my system.


I strictly followed this http://wiki.xbmc.org/?title=XBMCbuntu#Lo...nel_module guide in order to get everything working.

Furthermore, i followed this http://wiki.xbmc.org/index.php?title=HOW...controller guide in order to get my audio working.

It really does, but i am experiencing some audio playback problems. It seems as if menu sounds are not played properly (i can hear them, but they just don't sound like the ones on a Windows-based system [Skin is the same, ofc.]). It also happened that the menu sounds just disappeared after some time while movie playback audio was still working.

What can i do?


Kind regards!

Bump.

I created a .wav file that shows in which way my xbmc sound sounds corrupt. I actually can't describe it.

Please just take a look at this:

Thank you.

I just went through it again:

-installation of 11.04 minimal + OpenSSH for remote access
- installing alsa-utils by using

Code:

sudo apt-get install alsa-utils

(HDA NVidia available in alsamixer right now!)

-enabling any SPDIF-channels in alsamixer
-testing command:

Code:

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav

result: no sound can be heard, even when trying to replug the hdmi cable.
Displayed text:

Code:

xbmcadmin@xbmc-ubuntu:~$ sudo aplay -D plughw:1,3 /usr/share/sounds/alsa/Front_Center.wav
Wiedergabe: WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate: 48000 Hz, mono

editing the pcm.default to directly access my video card:

Code:

xbmcadmin@xbmc-ubuntu:~$ sudo nano ~/.asoundrc

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

rebooting.

retrying to get any sound out of my TV:

Code:

xbmcadmin@xbmc-ubuntu:~$ sudo aplay -D plughw:1,3 /usr/share/sounds/alsa/Noise.wav
Wiedergabe: WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little Endian, Rate: 48000 Hz, mono
xbmcadmin@xbmc-ubuntu:~$

still nothing to be heard.


edit:

retried it like that:

• installed minimal ubuntu 11.04 natty
  
• installed latest nvidia drivers from nvidia.com
  
• installed latest natty ALSA packages and unmuted any muted devices, both onboard and the hdmi device of my graphics card [via sudo alsamixer]
  
• tried the following:
  
  Code:

  xbmc@xbmclinux:~$ aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
xbmc@xbmclinux:~$
  
  Analogous speakers plugged in 0,0 --> i hear the sound
  HDMI cable plugged in 1,3 (the graphics card and my TV) --> i do not hear the sound.
  
  
• my user is in the audio group.
  
• I followed http://wiki.xbmc.org/index.php?title=HOW...controller this guide strictly
  
• when trying to verify what i did in the guide, this is being displayed:
  
  Code:

  xbmc@xbmclinux:~$ sudo speaker-test -D hdmi -c6 -r19200 -FS32_LE

speaker-test 1.0.24.2

So i just manually compiled and installed all recent alsa-files Version 2.0.4.

I have no clue why alsa-mixer showed me that its version is 2.0.3...


Back to my problem: The Sound sounds quite strange in my TV (which is a stereo one, atm). Is it possible that my HDMI cable transports a 6-ch audio signal causing that strange echoing-effect when playing that sound with my TV?

Another question: How many channels do the XBMC-Neon-Menu-sounds have? Are they simply stereo?
