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

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

Answer 1

just for fun....
hook the front panel stuff back up inside your computer...
Open the Realtek Audio Manager..
Click the Audio I/O tab..
just to the right of where it says Analog, there is a little blue dot...
Click it and click to disable front jack detection..
Then click the Front headphone picture on that page (make sure your headphones are plugged in)
make sure headphone is selected..
Do the same for the microphone...
then click the Mixer tab..
scroll along till you see Front Green In and Front Pink In
Make sure they aren't Muted and raise the volume level up..
If you have a microphone plugged into one of the jacks, click the tiny button to the right of the mute button to boost your mic...
Not sure if thats your problem but ..
that control panel is a nightmare...
Good luck
