ALSA and GTX 4XX Series - Page 3

hey astar, this is the line I put in /etc/pulse/default.pa in order for pulse to work with my gtx 480:

load-module module-alsa-sink device=hw:1,7

It created a new "device" in my pulse audio selection which always works for me. Instead of the device being called:
GF100 High Definition Audio Controller Digital Stereo
the new device is just called:
GF100 High Definition Audio Controller

It is never selected when I boot, but in the system it must be selected because without that line I cannot get working audio from pulse. Hope this helps! Its kinda odd since my last ubuntu install used device 3 instead of 7, oh wells it works.

omfg! It's so great - It works!
Thank you, very much. It helps a lot.

Any idea how to specify custom name for them? I'd like to add 2 outputs (via DP and HDMI).

Oh yeah, It's time to dance.

Code:

update-sink-proplist alsa_output.plughw_NVidia_8 device.description="Such a great new name"

check pacmd

AHH! I've been trying to figure out why I don't have audio (through HDMI) in console mode before starting X. I wonder if newer kernels and alsa drivers have corrected this?

Radiotubes,

No, I believe the requirement to be running X for HDMI audio to function will always be present.

Hi,
A new custom pc has a GPU Nvidia Gts 450 with hdmi out.
This pc is going to be permanently connected to an LCD TV.

During the first installation of Ubuntu 10.10 64-Bit, there was no sound through HDMI.
Following this post I managed to hear sound.

The problem is that the sound is distorted. Here is the info from the alsa-info.sh
http://www.alsa-project.org/db/?f=f0...05f2d65543a933

Any ideas or proposed settings for this problem?

Did you read this too: ftp://download.nvidia.com/XFree86/gp...dmi-audio.html ?

does removing your .asoundrc change anything?
You will loose your default assignment so use hw:1,7 directly.

Yes I did, but the thing is that i do have sound, which is distorted.

I tried once the very first time to edit /etc/pulse/default.pa, and add

Code:

load-module module-alsa-sink device=hw:1,7

If that is what you mean "directly", I couldn't hear any sound with this setup.
I will try once more and i will post here.

My point with .asoundrc was that it might cause distortion so it's better to remove it to check.

Can you try to do

Code:

mv ~/.asoundrc ~/.asoundrc.copy
speaker-test -c2 -D hw:1,7 -twav

no need to fiddle with PA config.

Does this also produce distorted sound? BTW, what kind of distortion do you get?

lampra · 04-02-11, 08:57 AM

Hi, it's been a while but I was out of town for a few days so i couldn't test it.

Well, you are probably right, direct use of hw:1,7 does not produce any distortion.

Could you please now propose a solution? Without the .asoundrc file there is no sound.

ps: i am not that fluent in English to be able to explain you the kind of distortion.

Update:
I followed this post
http://ubuntuforums.org/newreply.php...e=1&p=10232433
and i removed pulseaudio. Now the sound is crystal clear.
I had to install audiohacks (https://launchpad.net/~dtl131/+archive/ppa) to restore volume control.

Maybe not the best solution but it works fine. Any other idea?
