[SOLVED] New graphic card installed: the sound is now gone. how to solve?

floppy_stuttgart · 02-14-2015, 04:44 PM

hello,
I installed an ATI card into my pc, now the sound is gone. I suppose this is due to the position of that new card which is now "0" (when I start alsamixer, I see the sound default is "HD-Audio Generic" with "Chip: ATI R6xx HDMI". I dont have a screen on the HDMI. I just want to take the "Intel ICH6" with "Chip: Analog Devices AD1981B" as the default card as per previous installation.

What should I do?

cat /proc/asound/cards

Code:

 0 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xf0620000 irq 42
 1 [ICH6           ]: ICH4 - Intel ICH6
                      Intel ICH6 with AD1981B at irq 21

Thanks.

Hi, This may be slightly different on your system, I use Mageia and an nVidia graphics card.

What I do to stop the sound being hijacked by the graphics card > hdmi connector, is

blacklist the kernel module, so the hdmi sound is not loaded at boot.

I do this here... The name of the file maybe different on your fedora system...

/etc/modprobe/blacklist-mga.conf

Code:

# blacklisted modules for PCI coldplug
# see also /etc/modprobe.d/blacklist-compat

blacklist rivatv
blacklist bluetooth
# For some bridges both intel-agp and i82875p_edac are loaded. If i82875p_edac
# is loaded first it will grab the device. Then intel-agp doesn't work.
# Therefore we disable automatic loading of 82875p_edac. (Bug 213840)
# https://bugzilla.novell.com/show_bug.cgi?id=213840
blacklist i82875p_edac

# do not use "Boot Protocol" drivers, we prefer usbhid
# and they cause problems when loaded together with usbhid (#37726, #40861)
blacklist usbkbd
blacklist usbmouse

# disable PC speaker by default
# pcspkr is the standard driver, while snd-pcsp is the ALSA driver
blacklist pcspkr
blacklist snd-pcsp
blacklist nouveau
blacklist snd_hda_codec_hdmi  #hda-nvidia-digital-stereo
blacklist snd_hda_codec_realtek #hda onboard 5.1 surround
blacklist snd_hda_intel
blacklist snd_hda_codec
# Prevent conflicts with nvidiabl
blacklist nvidia_bl
blacklist nvbacklight
blacklist mbp_nvidia_bl
# End of entries added for nvidiabl

this module is the one I block snd_hda_codec_hdmi

You should be able to check with the lsmod command in a terminal, like konsole with kde.

type, you might need to be root

Code:

lsmod | grep hdmi

greping for hdmi will, I hope, only show any lines that have "hdmi" in them/it.

check to see if it's loaded before and after a reboot.

You need root (admin) privliges to save any changes to /etc/...

I use vi or nano to edit system config files as root.

I hope this helps.

regards Glenn

Thanks for the advices. Here are my current findings.
I am first testing the advice for blacklisting according post #2: I added and tried the bootcode "snd_hda_codec_hdmi.blacklist=yes"
The module snd_hda_codec_hdmi is nomore loaded (it dont appear in the output of lsmod).
But, the wrong chip still appear as defaultdevice in alsamixer "HD-Audio Generic" "ATI ID aa01" (different from the loaded card if snd_hda_codec_hdmi would have been loaded) and I still cannot hear the sound.
So, perhaps another module should be blacklisted. Which one?

floppy_stuttgart · 02-19-2015, 07:35 AM

a) After a second boot with "snd_hda_codec_hdmi.blacklist=yes", the sound is there! (it was not the case at the first boot.. curious..)

b) In any case, I made the try according Post #3 and #5 (no blacklist as boot parameter); I included
in /etc/modprobe.d/alsa-base.conf
...
# change 19 Feb 2015
# Keep hdmi outputof the radeon graphic card from beeing loaded as first soundcard
options snd_hda_codec_hdmi index=-2
#
...
It works! Thanks.

What I see:
- GOOD: the standard intel card of the PC
- no hdmi module is loaded as per Post #1 (no "hdmi" module can be seen with lsmod)
- the "HD-Audio Generic" "ATI ID aa01" can be seen as second card

My expectations with my comprehension of alsamixer, changing the file alsa-base.conf and interpreting the comments of that conf file would have been:
- the hdmi module would have been loaded
- the standard card is the intel
- the second card would be "HD-Audio Generic" "Chip: ATI R6xx HDMI" as per Post #1 (dont see this)
Whatever are my expectation, I am happy and it works!

GlennsPref · 02-19-2015, 10:46 AM

Hi, I'm glad you got it sorted.

I would have thought that the "pc speaker" was next to be blacklisted.

Code:

...
pcspkr                  1273  0 
...

Anyhow, all the best,

Regards Glenn

floppy_stuttgart · 02-28-2015, 03:23 AM

At a cold boot that morning (after 2 days of no use), the "HD ATI" sound card was loaded at first despite the contermeasure indicated in a previous post (I had the feeling it worked).
At a second boot, the sound of the "Intel" was there.
Curious behavior: hopefully I dont need 2x times boot for having the correct card loaded.
Lets keep observing that behaviour: I will log the first and second boot the next days and analyze this.

DavidMcCann · 02-28-2015, 10:31 AM

I've heard of this behaviour before in Debian-based systems. Try blacklisting by putting
blacklist snd_hda_codec_hdmi
in /etc/modprobe.d/blacklist.conf or whatever your system calls it, rather than using a boot parameter.

floppy_stuttgart · 02-28-2015, 04:21 PM

This was a bit like #6: at a cold first boot, the blacklisting in the kernel parameter did not work. But it worked at the second boot.
I blacklist now according #9 and will make a cold boot tomorrow and post the result here.
Just for information (no snd_hda_codec_hdmi module loaded):
lsmod (of wrongly loaded card)

Curious...

Blacklisting according #9 and a warm reboot (sound works) give another lsmod with a "1" and "17" marked in bold which deviates from previous lsmod (the "1" and "17" are coming up from a warm reboot and make it working? The "0" and "15" are a sign its not ok? I will have to understand what are these parameters in the "lsmod" output):

So, I blacklisted according #9:
- a cold boot: no sound available
- a second boot (hot boot), the sound is there
My thoughts: with a cold boot, the sound system is not coming up (slow hardware? capacitor empty and which needs more time?).
So, perhaps should I put a delay in booting for the system to have time to boot correctly?
How to put a delay? Any advice is welcome.

Update: during a cold boot, I included waitdev=5 into the grub command line and it booted with the sound.
Then, I included then waitdev=5 into grub via "sudo leafpad /boot/grub/menu.lst" then "sudo update-grub". Let see if it boots continuously with sound now (without editing the grub command line and at each cold boot).

Update: after a hot reboot of the previous successfull coldboot, the sound is gone. I'm still searching what happens..
(1) When during a cold boot (seen in dmesg) ...
snd_hda_intel 0000:06:00.1: irq 42 for MSI/MSI-X ...
ALSA sound/pci/hda/hda_intel.c:2713 0000:06:00.1: Handle VGA-switcheroo audio client ...
radeon 0000:06:00.0: irq 43 for MSI/MSI-X ... sound dont work
(2) but during a warm boot ...
radeon 0000:06:00.0: irq 42 for MSI/MSI-X ...
radeon 0000:06:00.0: radeon: using MSI. ...
ALSA sound/pci/hda/hda_intel.c:2713 0000:06:00.1: Handle VGA-switcheroo audio client ...
snd_hda_intel 0000:06:00.1: irq 43 for MSI/MSI-X .. does work

The question would be how to change the irq for both different module or how to change the load sequence for both modules. Perhaps I should remove the snd_hda_intel, reload it, and restart alsa (= effect would be the snd_hda_intel would be in any case a module loaded after the radeon like 2).

With blacklisting snd_hda_intel (additionally to snd_hda_codec_hdmi), the sound is there at each boot. Topic closed.

My findings:
a) sometime the processor is recognized as "tsc: Detected 3393.662 MHz processor" and the radeon driver was loaded before the snd_hda_intel. GOOD (sound working). I found out that snd_hda_intel dont need to be loaded in my PC for making the sound working.
b) sometime the processor is recognized as "tsc: Detected 3393.808 MHz processor" and the snd_hda_intel driver is loaded before the radeon driver. NOT GOOD (sound NOT WORKING).

I dont know why the processor is recognized differently (bad contact at the pin..?). I will not further search.
