HDMI-Sound gone after LMDE upgrade (solved)

[Eko_taas]

My TV-Mint was running OK
- LMDE updated around 10.6.2011 (working well, then traveling 2M)
- HDMI (picture, sound) OK with HDMI on LCD-TV (also in new location)
(HW: Dell Inspiron Zino HD with RS780 Azelia controller Digital Stereo (HDMI))
http://www.dell.com/us/en/corp/desktops/inspiron-zino-hd/pd.aspx?refid=inspiron-zino-hd&s=corp

When I found that MintUpdate claimed "packages broken", I run

Code: Select all

apt-get install -f && apt-get clean && apt-get update && apt-get dist-upgrade


All was looking OK and looks to be up to date (as per MintUpdate as well), but found no sound
(System Monitor: kernel 3.0.0.-1-amd64, Gnome 3.0.2)

I have checked sound settings several times
- not muted (100%)
- Sound Pref / Output "RS780 ....(HDMI) stereo"
- Sound pref /hardware Profile "digital stereo (HDMI) output"
- all sounds missing (VLC medial player, system sounds).

Where to start fixing?

Moved here from Hardware Support

Sorry for wrong location... Analoque headphones OK when selecting as active output...

Eko_taas,
I moved your post here as it is more likely to be seen by people who know about LMDE,and therefore may be answered quicker than if it had stayed where it was in Hardware Support

Thanks, waiting for innovative solutions to fix this.

To re-enable HDMI audio, in /boot/grub/menu.lst, add this to the end of your "kernel" line:
radeon.audio=1
...

Seems that good hint (as for radeon), but as newbie bit complicated to implement

In my LMDE, above file/folder does not exist (even if as sudo)

Have you checked "Sound Preferences" - "Output" - "Choose a device for sound output"?
Some times it switches the graphic cards.

As stated earlier, done as 1st thing... Also bottom selection (i.e. not "off")

Arch Linux uses "old" grub , Debian/LMDE "new" GRUB2. You need to edit another file - /etc/default/grub, and under
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" add radeon.audio=1, so it looks like
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1", and then run
sudo update-grub , and reboot

Thanks Man, you made my day worked like a charm

Makes me wonder, why this change has been done (or why GUI cannot detect this setting....

[sumski]

no problem i also find this change puzzling

That broke the frames around all of my windows (except chromium). I'm not certain how to search for this, can someone give me a pointer? I'm using LMDE with XFCE.

This might be related to the "Save session" -option, which was enabled at the time.

EDIT: Missing frames solved by typing

Code: Select all

xfwm4

in the terminal. Rebooted with "save session".

It worked for me, running LMDE-Mate with ATI Radeon 4650. No audio out of HDMI port despite using HDMI 1.4 latest standard with audio return channel or old 1.3 cable. Adding radeon.audio=1 to grub was the only thing who made sound go thru HDMI to TV. ++

And what is the corresponding GRUB command if you have an Intel chip?

/j

This might be of some help despite it being for ArchLinux. I think the concept of what you have to do is the same.

Run these commands:
aplay -l

Get the device info.

E.g. say, it is 'device 3.'

Create or edit asoundrc file. Put something like this there:

pcm.!default{
type hw
card 0
device 3
}

This is for using ALSA. If you want it for PulseAudio, read over the first ArchLinux thread and see if it helps.
