to use alsa you dont need a device name. the output is referenced by
cardid and output. e.g. hw:0,0 or hw:0,1

you have a second card for hdmi audio output

In this case this line should work:
> gst-launch playbin2 uri="myfile" video-sink="pvrvideosink"
audio-sink="alsasink device=hw:1,0"
As second step you can create an alsa alias for your hdmi device. check
your /etc/asound.conf (from details see alsa documentation)
> pcm.!default {
> type plug;
> slave { pcm "hw:0,0" }
> }
> pcm.!hdmi {
> type plug;
> slave { pcm "hw:1,0" }

than you can use the alias name
> audio-sink="alsasink device=hdmi"
hope this will help you.
PS: In general is this the same as on most desktop machines were the gfx
card has an hdmi output. Than you have always a second audio device for
hdmi audio only. So you have to set this device as you output device.
