It looks like your card is getting probed in both cases, unless you have 
an additional device that is not being listed.  The pcm0 device above 
looks to be from onboard sound on your nvidia motherboard, while the 
pcm1 device is the HDMI audio output on your graphics card.  My only 
suggestion here is to play with the sysctl hw.snd.default_unit:
$ sysctl -d hw.snd.default_unit
hw.snd.default_unit: default sound device

It defaults to 0, try 1-5 and see if there is any improvement, as you 
have multiple sound output devices.

What programs are you using to test the sound output?
