I was wondering because currently i see video. but i get no audio..On anything..No startup sound either..I didnt even know that existed because i get no sound on ubuntu 15.10..Im using HDMI.and i have a8 7600 APU. help.
Go to system settings > software and updates > additional drivers ... and see what graphics driver is in use, and see if there are any recommended drivers (proprietary).
On my Kubuntu 15.10 installation I had to activate the proprietary driver for my Nvidia card in order to get the sound working through hdmi.
Sounds more like a poorly supported audio chipset than a video issue. The radeon drivers are pretty reliable, and in fact AMD looks to be trying to phase out the fglrx proprietary driver. Or Canonical. Either way fglrx is not necessary.
''Im using HDMI'' may try the AMD Linux driver for its audio support over hdmi through the card I don't use the Linux driver from Linux I install the AMD Linux driver from AMD ??
sound through the card can be ''finicky '' anyway even with windows -- funny thing is I got a 7850 and it was working fine through the card and dvi-hdmi then one day I tried a newer driver I did not like it so I went back to the driver I was on and now the audio don't work ?? go figure
working fine before on the same driver it now don't work and all that was changed was the driver and then back to the know at the time working fine driver
Then you should be able to open pulse audio and there should be an option in the config tab drop down for hdmi out.
Though I'm working from memory here as it has been a while since I've done this so I may have forgotten a step.

ya that's my deal with Linux if I get something working I leave it alone too many steps to do a simple thing and then remember it all if not a everyday thing to be doing ..
seemed like I had to do the cards driver in Linux 2 or 3 times before I got it in right cause I missed or forgot a small step [plus I'm getting old and my mind my be slipping , lol.. ]
sad Linux cant come up with a universal point and click installer like with windows stuff all that work in terminal all the time like back from first days still
if Linux would band togher and make thing more user friendly with the way Microsoft is now they would grow in fan base and to be honest if it was not for ease of gaming I would probably ditch windows anyway that's all I feel its got going for it anymore is the fact they got such a strangle hold on game developers with direct x .. I think today that's all Microsoft got going for it
any way that card audio is funny I think with AMD its how the driver installed I may try to reinstall the driver to see if it starts back to working here as it did before I updated and went back .. cause it was working fine until I changed to a newer driver but after I went back to the working older driver it still don't work when it did before with out issue
ok it says HDMI and built in stereo.It says HDMI is plugged in. everything seems fine..but still no sound
Hmm make sure it isn't muted in alsa for some reason.
in the CLI type:
alsamixer
Should be SP/DIF make sure it isn't muted. (or just unmute everything)
@junkeymonkey: I hear ya there. It has certainly come a ways for default users in ubuntu etc. but god forbid you have fringe case or something like that. Then it stops looking so good for Linux "noobs" (for lack of a better term)
don't know I did another clean uninstall and did a custom install of just the AMD hi-def audio driver and still a no go -- my thinking on this is something in the newer driver just disabled it from working or a registry change that affected it from working ..
for me it worked fine on 13.12 no issues could just swap from speakers off the realteck on the mother board to the speakers on the monitor or what ever from the vid card now I cant - all shows installed and working as normal but cant select shows ''unplugged''
now I only used the newer driver for like 2 hrs to look it over then went back to the ''fully'' working 13.12 and seen I still lost the cards audio ??
I worked on this off and on a few times and don't get it I just don't see in 2 hrs of look over a newer driver caused my hdmi to go bad like that [I guess theres a super long shot it could ] but just seems funny to me
ya Microsoft must pay well to keep developers in dx
I was looking for the article on how Microsoft ''won'' them over to dx [$$] and keeps them bound to it - even at the early times where open gl was better by far
anyway I guess I need to do some more head scratching on that card audio deal I got one more thing to try but don't have time today yet ...
If your monitor has an analog line-in, you can run audio from the computer's line-out to it with a male-to-male stereo cable. You would need to select either the stereo-duplex or stereo option in Ubuntu sound settings and turn-off hdmi sound setting. Then in your monitor's on-screen settings choose the line-in for audio. You shouldn't need to do anything with alsamixer.
If you have installed the pavucontrol, that is the one to use for sound settings. In the output config tab turn-on either stereo or stereo-duplex. Scroll down and turn-off hdmi sound (there might be 2 dropdown menus for it). This is for the line-out to line-in on the monitor. Your monitor should allow you to use hdmi for video while using line-in for audio. If the monitor doesn't have a line-in then you are forced to make hdmi audio functional.
I'm not recommending this, but if it were my computer... I would choose an older version of Ubuntu, probably Xubuntu 14.04 or Linux Mint 17.3 XFCE or Mate and replace Ubuntu 15.10. Driver installation and sound setup are easier on Mint and the older kernel is likely to be more friendly to AMD apu's. But that's just my opinion.
As other replies have said, this is likely a driver issue that may be unique to only the newer kernel/desktop.
