No HDMI audio using Ubuntu 13.04 and Radeon HD 4670

What is 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

Thanks

The script said that my ALSA informations are located at

http://www.alsa-project.org/db/?f=432302e0df7948cc0d8c06b51eac7228283fea0b

and pleased me to inform you of this..... o_O

Do you use the onboard sound. If not then I suggest you disable it in BIOS

Thanks for the help you're giving me.
I don't know, I suggest I do, but not intentionally, I never cared of setting it.
From jaunty jackalope to quental quatzal I just had my samsung 26" tv-monitor plugged into my video card through a HDMI cable and I just needed to select HDMI device into the Sound settings window.
I will give it a try, but...how? What am I looking for? The BIOS menu isn't very friendly to me, being a kind of newbie.

The BIOS is OS independent and is loaded before any OS.

You mention jaunty to quantal. Did you upgrade directly from jaunty to quantal in one jump, or did you upgrade through each successive release?

Hello,
I always upgraded through successive release, of course, no "big jump".
I found in the BIOS -> Integrated Peripherals -> HD Audio Controller, it was [Enabled]. I [Disable] it and reboot.
I don't have sound, nor devices in Sound Settings: before disabling it I had Digital output (S/PDIF) - Internal audio" and "Analog output - Internal audio".

I re-run the ALSA-info script, here's the output:
http://www.alsa-project.org/db/?f=527cc4d2cd1567ef759fabfcfec49f67aca6228d

Moreover, here's a output that can help:
ale@beast:~$ cat /proc/asound/cards
 0 [HDMI ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfeaec000 irq 45
ale@beast:~$

Anybody, please?
In Windows HDMI audio is working properly....

I'm providing more information, as I tried the following kernels:

3.10.0.rc1 ---> Ubuntu doesn't even start
3.9.2-generic ---> yes analog audio, no hdmi audio
3.9.1-generic ---> yes analog audio, no hdmi audio
3.9.0.rc8 ---> yes analog audio, no hdmi audio
3.9.0-generic ---> yes analog audio, no hdmi audio
3.8.0.20 ---> yes analog audio, no hdmi audio
3.8.0-generic ---> yes analog audio, no hdmi audio
Do y'all still think it's a kernel related issue?

Moreover, the system always recognises my audio/video card:
ale@beast:~$ cat /proc/asound/cards
 0 [SB ]: HDA-Intel - HDA ATI SB
                      HDA ATI SB at 0xfe9f4000 irq 16
 1 [HDMI ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfeaec000 irq 45
ale@beast:~$

Whenever I open a multimedia file in VLC, if I right-click and choose Audio -> Device, I can see my radeon HDMI. But Not in the Ubuntu Audio Settings!

Then, practically every day the software updater makes me install "HDA driver in DKMS format" 316KB.
The technical details are:
"Version changes in oem-audio-hda-daily-dkms:
Version installed: 0.201305151526~raring1
Versione disposable: 0.201305162023~raring1
This update doesn't come from a source that supports changelogs."

This is my file /etc/default/grub:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

I added "radeon.audio=1" like this in /etc/default/grub:

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="radeon.audio=1"

[and then the rest of it...]

I rebooted the system, still no HDMI audio

This could be the cause of the problem. This package is not normally installed by default. Since you have been upgrading from release to release this package is probably left over from when you were testing/attempting to fix another sound issue.

Also, the upstream 3.12-rc3 kernel contains a patch titled "drm/radeon: fix hdmi audio on DCE3.0/3.1 asics" which is relevant to your [AMD] nee ATI RV710/730 HDMI Audio [Radeon HD 4000 series]. Enabling HDMI audio on Radeon hardware has become easier in the 3.12 kernel. Instead of adding radeon.audio=1 to your GRUB kernel boot options, you can enable/disable HDMI audio on the fly with xrandr. E.g., xrandr --output HDMI-0 --set audio auto

You can obtain a PPA oif the 3.12-rc3 kernel at http://kernel.ubuntu.com/~kernel-ppa/mainline/ and instructions on how to install and uninstall it are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds
