HDMI audio on default alsa device in xubuntu

Question

My new monitor (Asus MX279) have 2 speakers and audio input from HDMI. In xubuntu 12.10 it doesn't work by default.

I identified the correct device with aplay -l and sound works great with

speaker-test -c wav -D plughw:1,7

and

aplay -D plughw:1,7 myTest.wav

Now, how can i set this device (in this case card 1, device 7) as default audio device? I've tried creating ~/.asoundrc like this:

pcm.!default {
    type hw
    card 1
    device 7
}

and restarting alsa with sudo alsa reload, or rebooting system but it did not work.

Thanks so much.

Solution

Solved!

I've created file /etc/asound.conf in this way:

defaults.pcm.card 1
defaults.pcm.device 7
defaults.ctl.card 1

and rebooted the system.

remember: in my case "1" is the card number and "7" is device number found in aplay -l output.

Case. Closed.

See ya!
