No HDMI audio output

Postby mint092513 on Wed Sep 25, 2013 7:49 pm

I am using Linux Mint 15 on an HP 3125 netbook. When I hook up the hdmi to the TV I can get the picture on the TV, but audio does not transmit to the TV.

1) I read and followed the recommendation in the release notes, but that did not provide the solution.

2) I read that someone corrected this problem by downgrading to Mint 14, but I also tried that and my wireless network stopped working.

3) I read that someone fixed this by upgrading to kernel 3.10 and I upgraded the kernel, but this did not solve the problem. I also tried 3.11 and 3.11.1, but I did not have wireless networking with those kernels installed.

4) Looking at screen shots and videos of people switching to hdmi output I see there is a application called sound in settings. This does not exist on my computer. Is this normal for version 15 or what am I missing?

5) I used audio mixer to change my audio device, but I don't think it really does anything besides change volume. I never lose audio if I change the selected device. HDMI does show up as a device though.

6) I installed pavucontrol, but this doesn't seem to do anything for me other than volume control.

7) I ran pacmd list-sinks and found something that is interesting to me, but I don't know what to do with the information

It says the hdmi audio is suspended because it is idle. This state doesn't change even when plugged in to HDMI and video running.

Any further ideas or how to unidle HDMI device?

An update. I tried a few more things today.

I am now able to select HDMI digital output to make audio go to the TV, but the TV still does not play any sound. The sound stops coming from the notebook speakers though. When I disable HDMi output it comes through the notebook speakers or set it to analog then it comes the notebook speakers.

I will continue my attempts and post more updates. Please give any ideas.

Re: No HDMI audio output

I had similar problem with Acer E1 Intel HD VGA, I had no HDMI option in sound settings and resolved it with this fix:
Code: Select all
https://launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages

I downloaded "oem-audio-hda-daily-dkms_0.201309280823~ubuntu13.04.1_all.deb" and after restart the HDMI option came up in settings and sound is working ok.
Maybe it can help you also, give it a try ;)

Do you have the latest drivers installed for your Radeon card? I once had the same exact problem, until I installed the drivers for my card and selected that card as the audio device when I connected it to my tv.

If you are still having problems, try this;



Re: HDMI Audio Issues

From https://bugs.launchpad.net/ubuntu/+sour ... bug/864735

Since kernel 3.0, upstream has disabled audio output for all ATI cards in the Radeon driver by default.

Edit /etc/default/grub and change this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to this line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1"

Now run "sudo update-grub", then reboot your computer.
