I have found it better to use the command "aplay -L" to list the available devices since
the output can be then used to directly test.

I am using an nVidia card with the nVidia drivers so the relevant portion from my system
would be

hdmi:CARD=NVidia,DEV=0
    HDA NVidia, HDMI 0
    HDMI Audio Output
hdmi:CARD=NVidia,DEV=1
    HDA NVidia, HDMI 1
    HDMI Audio Output
hdmi:CARD=NVidia,DEV=2
    HDA NVidia, HDMI 2
    HDMI Audio Output
hdmi:CARD=NVidia,DEV=3
    HDA NVidia, HDMI 3
    HDMI Audio Output

I have 2 ASUS PB258Q monitors.  One is connected to an HDMI port and the other the display
port.

To play on the HDMI connected monitor's speakers I can use...

[egreshko@meimei ~]$ aplay -Dhdmi:CARD=NVidia,DEV=1 05-Born_To_Run.wav
Playing WAVE '05-Born_To_Run.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

To play on the DP connected monitor's speakers I can use...

[egreshko@meimei ~]$ aplay -Dhdmi:CARD=NVidia,DEV=2 05-Born_To_Run.wav
Playing WAVE '05-Born_To_Run.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

But I have Bose external speakers so I never use the monitor speakers as they sound
horrible in comparison.  :-)
