post #16 of 23

I was using Creative Sound Blaster X-Fi Titanium Sound Card when my PC was still alive, now I have HP 630 laptop, and Ubuntu says:

 

00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)
    Subsystem: Hewlett-Packard Company Device 3672
    Flags: bus master, fast devsel, latency 0, IRQ 44
    Memory at 92600000 (64-bit, non-prefetchable) [size=16K]
    Capabilities: [50] Power Management version 2
    Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
    Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
    Capabilities: [100] Virtual Channel
    Capabilities: [130] Root Complex Link
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd-hda-intel

 

On same laptop for Windows I am using Realtek High-Definition (HD) Audio Driver and It works fine, When I am using Ubuntu 12.4 I am receiving half loud sound nearly, Now might be configuration problem, but on my PC I noticed little difference between these two OS...

 

Do you know any solution?

P.S. I have compared performance of 50 hz sine wire sound, used this test http://www.eminent-tech.com/music/multimediatest.html, and difference was clearly noticeable, on Win I received much clear much better sound.

Realtek HD codecs are generally well supported. Check the mixer settings, and that you are not using a line output for driving headphones.

stv014 sorry you might mean checking on Windows but I don't have any problem with Realtek on Win, it works fine, I think Ubuntu have some incompatibility with my sound card... For example when I tested 50 hz sine wire I received different sound quality on Ubuntu, even left channel was more sharp then right, first time I thought it was my headphones problem but when I restarted and run Win everything was fine, besides sound loudness on Ubuntu is 70% than Win,

 

Thanks for reply

I meant check the settings on Linux. Even if your onboard audio is not well supported, it would be surprising for that to result in different sound on the left and right channel.

Yes, checked I think everything is fine,  I updated system using apt-get update But nothing, It is very surprising for me too confused_face%281%29.gif

Lemos,

 

HP's website info for your laptop model doesn't specify what type of motherboard audio chip is installed, but it does say it supports Suse Enterprise Linux 11. I'm not sure where Realtek sound drivers come in for an Intel HD Audio chip. However, a quick Google search of your "HP630 and Ubuntu Linux" shows that others are having audio issues. You might try the solution offered in the second post here: http://www.linuxforums.org/forum/ubuntu-linux/190338-audio-problem.html

 

Without more specific info on how you have your Ubuntu OS set for sound output, its hard for anyone to offer more helpful advice.

Intel HD Audio is not a chip, but a standard for onboard audio that replaces the old AC97 interface.

You're absolutely correct. I understand that the motherboard audio chip is made by many different companies (Realtek being one) and that Intel HD Audio is a specification for chip makers to follow, it just didn't come out that way when I wrote my reply. As politicans love to say "I mis-spoke", or in this case, "mis-wrote".wink_face.gif
