Where are your speakers attached? Are they built into the monitor? Or are you using an external speaker set connected to the analog pins?
 
I have 3 audio outputs, realtek to my headphones, Nvidia hdmi to my screen and Emotiva ta-100 integrated amp with built-in dac that I use as my main audio device. I would like to get them all working if possible but the external usb dac is the most important one.
 
$ mixer
Mixer vol is currently set to 100:100
Mixer pcm is currently set to 100:100
Mixer speaker is currently set to 74:74
Mixer line is currently set to 1:1
Mixer mic is currently set to 67:67
Mixer mix is currently set to 74:74
Mixer rec is currently set to 35:35
Mixer igain is currently set to 0:0
Mixer ogain is currently set to 100:100
Recording source: mic

mixer levels all seem to be ok too, so that must not be it. Just can't figure this one out...
 
sysctl hw.snd.default_unit=6
cat file_example_WAV_1MG.wav > /dev/dsp
doesn't still produce anything audible...
 
/dev/dsp is connect to a virtual_oss(8) device, that's for bluetooth audio. Focus on the connected pcm devices first. Figure out which of the pcm is connected to your monitor. Each of the 4 devices (pcm0 to pcm3) corresponds to a particular display connector on your video card. You'll have to test which one corresponds to the connector that's actually connected to your monitor.
 
pcm2 is my nvidia -> screen. that works when outputting to that device from vlc and gnome settings has /dev/dsp4 selected for audio output. Gnome itself is unable to output audio and web browsers too, since I don't know how to select device from the browser for outputting sound. There are 18 virtual audio output devices one can select from vlc and 6 dsp devices in gnome settings. I guess I now have to find the right combination to get my dac working... sigh
 
I got my dac working by sending nvidia->screen->optical out->dac. Not ideal but at least some progress. Thanks for the help.
