Hi all,

I am the guy with the previous post about not being able to access the CDR. Well, I got that resolved but I still have a problem with audio.

I have a NVidia NForce 4 motherboard that has integrated audio and video. Earlier I had everything working on R5A30.2 except that the playback of HD video was a little jittery. I didn't notice it but my wife thought it was awful. After I thought about and she complained, I realized it was there and it bothered me as well.

I decided to bag the on-board 6150 video and bought an NVidia 6200 TC PCI-X video card. I installed it and it acted exactly the same. So I decided to downgrade the video driver from 8178 to 7174 because a friend with a Myth box said that he read that the new 8xxx NVidia drivers are problematic.

After the downgrade the video was all screwed up and I just thought oh, I will try to upgrade to R5B7 and try it out. After the upgrade, I can't get any audio. With the R5B30 I also didn't have audio, but when I installed the latest realtek Linux drivers from their website, audio started working.

So I installed the realtek drivers on R5B7 and the audio still did not work. If I type alsaconf it says that it cannot find any audio devices.
So I re-upgraded R5B7 again and now I can say alsaconf and it finds a Intel something or other audio device, I select it and it goes through the process properly and ends. However, I still have no sound (analog hookup). Another piece of info, If I type alsamixer it errors out and cannot come up.

I know that when I had R5A30 alsamixer came up and let me adjust the volumes. I am not in front of the box right now so I can't give the error that alsamixer comes up with. I will put that in the next post.

Any ideas what has changed?

Thanks,
Rick Wirch

Oh by the way here is the hardware with the audio problem:

Gigabye K8N51PVMT-9 motherboard with realtek 880 audio and NVidia NForce 4, NVidia 6150 video integrated.
1 GB Kingston memory as 2 512 MB PC3200 dimms.
AMD Athlon 64 3200+
Seagate 300 GB PATA hard drive
NVidia 6200TC PCI-X video card
HD3000 HDTV tuner card
Toshiba 34HF81 34" Picture tube 16:9 HDTV connected via component.

It is basically the same thing as a 'dragon' box except for the motherboard, but I have been struggling with this since January to get it to work. I have 2 friends who have made Myth boxes and they both have them working, however one is SDTV, and the other bought a Dragon box.

Hi wirchrick,

Glad to hear the "other" thread is satisfactorily completed

Audio has been an issue with me a couple + times also. It just won't work with some hardware or if you do get it to fly it isn't right. I have an ASRock with those kind of ...

Anyway, run as root alsaconf and take notes, could be valuable sometime down the road.

from the fe:
alt x
su -
passwd
alsaconf

after it finishes, you should be able to play sounds...

if not,
alsamixer
check all muted / unmuted controls as one should bring it back.

Mine would load snd_intel8x0 & snd_intel8x0m, it was the "m" that kept killing it after a reboot and I never got rid of it til R5B7. Now it comes up snd_intel8x0.

Maybe this gives you something go on.

Hi all,

When I do a 'alsaconf' the audio shows up as this:
hda-intel 0000:00:10.1 0403: nVidia Corporation : Unknown device 026c

I then select that, press OK twice on next 2 dialogs.
It then says 'sound driver is configured 92%' I press OK.

Then a bunch of 'hda_codec: num_steps=0 for NID=0xb' lines spill out
followed by this line:
/usr/sbin/alsactl: get_control: 185: Cannot read control info
'2,0,0,Front Playback Volume, 0' : Invalid argument

If I try to do a 'alsamixer' I get this output.
hda_codec: num_steps=0 for NID=0xb
alsamixer function snd_mixer_load failed: invalid argument

Any ideas? One thing I need to check is that I think that I don't have my front audio or USB ports connected to the motherboard. Maybe that didn't matter in R5A30 but R5B7 now is un-happy because the front input/outputs are not connected?

Thanks,
Rick

Hi

You did say "realtek 880 audio" earlier ? And that you added a nvidia card ? May be some sort of hardware confict or the nvidia is confusing the config tool. If you can discover which drive the 880 uses, you could try a direct, modprobe snd-???? to see if that may work. lspci should show if it sees the audio, a look at the modules may offer a clue also, lsmod

If you decide to pull the video card, you should be able to change the XF86Config file before reboot so you can still use the xserver.
Driver "vesa"
put a # in front of the current driver,

Other wise, I can't offer much more help for the moment.
