aplay -D plughw:0,3 rickjames.wav

Playing WAVE 'rickjames.wav' : Unsigned 8 bit, Rate 22050 Hz, Mono

NO SOUND!, however executes command no errors

aplay -D plughw:0,1 rickjames.wav

Playing WAVE 'rickjames.wav' : Unsigned 8 bit, Rate 22050 Hz, Mono

However NO SOUND!, I'm aware this IS not my HDMI output, however I believe it's relavent to diagnosing the issue.

I have sound normally, say playing a movie from VLC thought laptop speakers.

This is to show that alsamixer is not mute

Turn on and Off

https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#HDMI_Output_Does_Not_Work wrote: If aplay does not output any errors, but still no sound is heared, "reboot" the receiver, monitor or tv set. Since the HDMI interface executes a handshake on connection, it might have noticed before that there was no audio stream embedded, and disabled audio decoding.

yup did that, and i made sure the volume is on

Restart Alsa

https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#HDMI_Output_Does_Not_Work wrote: You can restart alsa with the example below or you may reboot, and audio should now work.

Nope unfortunately it didn't

Can someone help PLEASE.

One of the underlaying problems is that i do not understand what Pulseaudio / OSS are and what they do.

I've installed both, and i have pulseaudio server running.

Other side notes

- dbus is in rc.conf

- nVidia Driver: 280.13
