Bad quality sound NVIDIA 6100

[kastanedowski]

I am new in Ubuntu and I am using a NVIDIA 6100 card that seems to work fine with the graphics... but the sound is too bad, should I try to install any new driver?

anyone has the same sound isues with nvidia cards?

I am using the same computer with wndows and the difference is amazing, I am reading since 2 weeks how to fix such a bad sound and tried a lot of things , I am quite desperate and thinking that Ubuntu really needs engeneer studies

any help will be welcome, thanks

You should create a new thread outlining your problem rather than hijacking someone else's thread for a different problem.

Hi Coop

Not trying to create problems but looking for answers.

The threat is about installing "Nvidia driver", because a "new user" doesn't know how,in the same sense I have no idea if my problem of "bad quality sound" for Nvidia is due to the driver that affects graphics.


Question again, does installing this Nvidia driver affects the sound too? or just the graphics.

Thanks

It is part of the forum etiquette to not post your own DIFFERENT question in someone else's thread. Rather, you should start your own thread detailing YOUR problem and then we can help you to address it.

It seems a mod has intervened and created a thread for you now. Nvidia graphics drivers have nothing to do with sound, they are for graphics cards only. Sound drivers for nvidia are supported by ALSA.

I coop, thanks for the answer, that really gives me a better idea how to improve the sound.


In a Spanish forum I have found that Alsa makes everything to 48Khz, that makes the system really faster but has a horrible quality and they are recommending to "jump the filter dmix" so the kernel can work directly over the sound.

"h t t p : // foro.powers .cl /viewtopic. php?f=1&t=256273"
(I can not post links so join the spaces)

so I will ask you for your comment, why using the kernel to do the ALSA's job? wouldn't be better to change the 48Khz into 128Khz at least?
someone has idea how?


Writing "asoundconf list" I can see that I have a NVIDIA sound card, and I am pretty sure that the Nvidia driver should work,right?

so, "NVIDIA-Linux-x86-185.18.31.pkg1.run" should help for the sound??

Thanks for your comments

those nvidia drivers are not for sound, they are for the graphics card

48KHz is more than sufficient for the human ear (Audio CD's are 44.1KHz). Preadjusting the KHz on input to all the same value makes it easier to mix the sounds together from different sources at the same time. It just makes sense, though you can get a quality issue when the adjustment is not in whole-number step with the source... say mixing up from 12KHz to 48KHz should produce zero quality loss, but mixing from 22.05KHz to 48KHz, if an anti-aliasing filter is not applied, will cause clicking and other sound quality issues. ALSA usually deals with this pretty well, but there are some situations, usually involving older or cheap hardware, where there's just little that can be done about it.

If we look at what you actually have for hardware, what kernel module is driving the hardware, and what your ALSA version is, we can look to see if it's a know issue with a fix. Please open a terminal window and post the output of the following commands:

lspci -nnk | grep -iA 2 audio

aplay -l

cat /proc/asound/version

I have been googling for information and tried everything I have found, any advices will be really welcome, thanks!

It appears that chipset (ALC880) causes different problems for different people as related to ALSA. Are there certain programs or combinations of running programs that cause worse audio than others, or do all programs cause poor sound?
