<snip> I've newly installed ubuntu 14.04 on to a Gigabyte GA-J1800N-D2H board, and am trying to get sound working with a Samsung S24D590L monitor through the HDMI cable. Pulse audio control detects Port: HDMI / DisplayPort (plugged in), and the volume meter is showing it is responding to the levels, but no actual sound can be heard. Alsamixer shows the card as HDA Intel PCH and the chip as Intel Valleyview2 HDMI, and I've checked nothing is muted. Monitor volume is not muted. There is no output from "beep". </snip>
I was asked for the output of wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh --upload, which is now here: http://www.alsa-project.org/db/?f=1a91c118837f2f6038ddb73c397dae4bf340e0b5
Something else to consider is whether the output is set to analog or digital. It sounds a bit unlikely but if you're [somehow] routing analog audio output over your HDMI connection you wouldn't hear anything, and the logs do happen to show this in a few places:
Node 0x02 [Audio Output] wcaps 0x41d: Stereo Amp-Out Control: name="Front Playback Volume", index=0, device=0 ControlAmp: chs=3, dir=Out, idx=0, ofs=0 Device: name="ALC887-VD Analog", type="Audio", device=0 ^^^^^^ Just a thought.
Thanks for having a look, and your comments. I did ask my client to try plugging in external speakers through the back of the monitor, and voila! Really stupid of me - he told me he'd bought a monitor with speakers (thinking he had), so I didn't check. Sorry to time waste.
