That's what the "boot override" option does, overriding the sound card's pin assignments on every boot.
#ALC898 DRIVER PATCH#
The tool generates a firmware patch (under /lib/firmware/hda-jack-retask.fw ) entry that's also called up by a module configuration file (under /etc/modprobe.d/nf or similar), whose settings are applied on every boot.
The default channel map option for 5.1 audio should be set as: front-left,front-right,lfe,front-center,rear-left,rear-right Ensure that enable-lfe-remixing is set to yes. For 5.1 channel sound, set: default-sample-channels = 6 Of note is that for /etc/pulse/nf, the following changes must be made (with your preferred text editor): Note that this tool, depending on your sound card, will most likely detect them by the color panel layout (see the back of your card and confirm if its' pins are color coded) or by the jack designator.Įither way, when you're done and you select "Apply", you'll need to reboot and the settings will apply on the next startup.īefore you reboot, confirm that pulseaudio is configured to utilize the channel layout as desired. When done, launch the tool with administrative privileges as shown: gksudo hdajackretaskįrom here, you'll then need to re-assign each required pin.
#ALC898 DRIVER INSTALL#
The tools are installed by running: sudo apt-get install alsa-tools-gui pavumeter pavucontrol You'll want to use a tool such as hdajackretask, pavucontrol and pavumeter for the pin re-assignments and audio output monitoring afterwards respectively. For one, there's no Realtek HD Audio control panel here, so what gives? How do you around this problem? On Linux, however, its' a wholly different ballgame. Setting up analog surround sound on Ubuntu Linux with a 3 3.5mm capable sound card:Ī while back, I received the Logitech Z506 Speaker system, and with Windows, setting it up was a pretty plug and play experience.
