In certain cases I might have an older kernel or release of Ubuntu where my sound driver might be too old or buggy, how can I get updated sound drivers for my built in Intel Audio chip? Following these instructions will give you the latest ALSA driver, but only for internal "HDA Intel" sound cards if your computer is from or newer, you almost certainly have a "HDA Intel" sound card for handling internal speakers, headphone jacks and microphones. USB or Bluetooth sound will not be affected. Under the new section "Package files", click the file ending with ".

Although Linux has been supporting HD-audio since long time ago, there are often problems with new machines. A part of the problem is broken BIOS, and the rest is the driver implementation. This document explains the brief trouble-shooting and debugging methods for the HD-audio hardware. The HD-audio component consists of two parts: the controller chip and the codec chips on the HD-audio bus. Linux provides a single driver for all controllers, snd-hda-intel. Since the HD-audio controllers are supposed to be compatible, the single snd-hda-driver should work in most cases. But, not surprisingly, there are known bugs and issues specific to each controller type. The snd-hda-intel driver has a bunch of workarounds for these as described below. A controller may have multiple codecs. Usually you have one audio codec and optionally one modem codec. In theory, there might be multiple audio codecs, e. This should be fixed in future if such hardware really exists.

Else, look at the association list for this widget and repeat the process to examine the next widget in the path. The intel hda driver line should contain three numbers indicating the codec vendor-id 0x in the examplethe codec subsystem-id 0xabcd and the address 2 of the codec.

Ubuntu, a popular Linux distribution, is known for its robustness and flexibility. This article will guide you through the process of installing updated Intel HDA sound drivers on Ubuntu. Choose the solution that best suits your situation and follow the provided instructions. Intel HDA is a specification for audio codec hardware. The dpkg -i command installs a package from a. These modules may include updated sound drivers. Here, uname -r prints the current kernel version, and linux-modules-extra- is a package that contains extra modules for that kernel version.

Since the HD-audio controllers are supposed to be compatible, the single snd-hda-driver should work in most cases. When BIOS reports the available codec slots wrongly, the driver gets confused and tries to access the non-existing codec slot. Sorted by: Reset to default. Another related problem is the automatic mute of speaker output by headphone plugging. A less often but a more severe problem is the codec probing.

But before trying to fix problem that way, make sure that there really is a problem and that the PCM audio device in use really corresponds to the expected audio connector. Ubuntu Community Ask! The paths that are potentially useful are the ones that lead from pins with output devices connected to them back to a DAC, plus all the paths from those same pins back to all other pins with an input device connected to them some codecs allow inputs to be mixed into outputs for such purposes as karaoke, so your device driver might as well make this option available if the codec supports it , plus all the paths from ADCs to all pins with an input device connected. Note that this config will override even the driver pin configs, too. I do not accept the terms in the license agreement.
