HDMI sound whit Linux

When you want all your sound from your notebook or desktop you can use this. Its works fine for ATI and Intel, i dont know if it works on Nvidia.
3. aplay -l lists audio devices:
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC883 Analog [ALC883 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC883 Digital [ALC883 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI]
Subdevices: 0/1
Subdevice #0: subdevice #0
...from this, you can see that determine that HDMI out will be plughw:1,3 (that is, card 1, device 3). As mentioned above, it has to be plughw, not just hw.
4. Run sudo alsamixer -c 1
5. There's no option to raise/lower volume, but you can un-mute by hitting 'm'. If you see a box at the bottom of the terminal window with 'mm' in it, you're muted. If it contains '00', you're un-muted.
6. Hit esc to quit.
7. Run aplay on a .wav file to test, like so: sudo aplay -D plughw:1,3 . If your device number was different, use that.
8. Assuming that all works, edit /etc/asound.conf (which may not exist yet), put this in it:
pcm.!default {
type hw
card 1
device 3
}
Again, use your device numbers. Now the 3200 HDMI is your default audio out.
The Alsa wiki page on Digital Out (http://alsa.opensrc.org/index.php/DigitalOut#MythTV) was super-helpful.
When you want to change back to your normal default audio, you can use these shortcut.
alias alsalaptop='sudo mv /etc/asound.conf /etc/asoundconfbak'
alias alsahdmi='sudo mv /etc/asoundconfbak /etc/asound.conf'
alias alsareset='sudo service alsa-utils stop && sudo alsa force-reload && sudo service alsa-utils start'
when you type in the terminal terminal alsahdmi and after that alsareset then you switch to HDMI, whit alsalaptop you switc back again.

Het enige is dat je HDMI card nu ook je standaard audio uitvoer apparaat is, dit is op gelost door snelkoppelingen te maken met alias in .bashrc
[code]
alias alsalaptop='sudo mv /etc/asound.conf /etc/asoundconfbak'
alias alsahdmi='sudo mv /etc/asoundconfbak /etc/asound.conf'
alias alsareset='sudo service alsa-utils stop && sudo alsa force-reload && sudo service alsa-utils start'[/code]
Als ik nu in de terminal type alsahdmi gevolgd door alsareset dan schakel ik over naar HDMI, met alsalaptop schakel ik weer terug.

I used the tutorial, but it only got me halfway. I can play vaw files with aplay and I get sound out from VLC. But the system sounds (login, logout, error and so forth) does not work.
I used it on LMDE whit Gnome, but i think it should work on other versions to.
Whit pulse i think you can change alsa to pulse, but i dont know for sure. I dont use pulse it wont work good for me.
What version of mint does this relate to? How does it work with pulseaudio?
