Hi
After days of trying everything I have found in forums I need your advice (HELP)
I have the same computer with windows and the sound quality is too different, I have gone to my sound preferences and in "automatic" I can hear the sound but not in "HDA NVIDIA".
ALSA is supposed to do the job and I actualise it but the same...
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?
Here the details of my computer and system
These are the results:
