Are there any Realtek audio drivers for Ubuntu? If yes where do I get them and how do I install them correctly? (for Ubuntu 14.04 64bit) Also with jack work okay after I install them?
Curious about the reason? The ALSA drivers don't support microphones for my soundcard (Creative Sound Blaster 5.1 VX). Also, It does not handle audio output quite well. I have issues. Also, I'd really like some software like the windows-only "Realtek Audio Manager" that does effects to the audio such as echoes and so on.
The best thing to do would be to remove alsa and reinstall it. The same thing happened to me when I switched motherboards, and this fixed it.
Remove the ALSA packages.
Reinstall the same packages.
Packages gdm and ubuntu-desktop are also removed in this process if you are using Gnome. They need to be reinstalled:
If you are using Xubuntu this will also happen to you.
Reboot.
I had the same problem (internal mic not working) with my Lenovo Ideapad 320, which runs Ubuntu 18.04.
I installed GNOME ALSA Mixer from the Ubuntu Softwares Panel and followed another topic instruction: put the "Capture" full on the right and "Internal" empty on the left, as the following image:
It worked well for me.
Install Pulseaudio Equalizer for purposes:
Your sound card Realtek may have problems frequencies. To solve install OSS. It seems that it is supported. Download from here. Install and restart.
If installation errors, install
alsa-oss
