Driver Audio by Bang & Olufsen ... Help.

Support Driver and Hardware
1

Good morning,
a few weeks ago I decided to install exactly the HP EliteBook 840 G3 Notebook - with i5 6200 processor (https://support.hp.com/us-en/document/c05259054) – linux Parrot 6.1 on a (slightly dated) notebook. Once installed, everything seems to work except the audio. This notebook has “Audio by Bang & Olufsen” drivers and from reviews found on the internet it seems that they have created problems for various Linux versions.
Considering that I’ve been using Linux in general for about two weeks, could you help me solve my problem?
Thank you

  • Parrot version in use (if you are not aware of it, open terminal and type cat /etc/os-release | grep VERSION):

  • Kernel version (if you are not aware of it, open terminal and type uname -r):

  • Logs/Terminal output (use pastebin or similar services):

  • Screenshots:

Sound on HP’s is often a problem beit laptop or desktop, and to make it harder you have B&O sound, the following is one possible remedy which I understand often works for B&O

 Steps for fixing the Bang & Olufsen speakers is as follows:

    Open a terminal window.
    Run sudo apt-get install alsa-tools alsa-tools-gui.
    Run hdajackretask.
    At the "Select a codec" drop-down list, choose Realtek ALC245.
    On the right-hand side of the hdajackretask window, click on the checkbox "Show unconnected pins".
    For each pin, you will either have to click the "Override" checkbox and then change the configuration using the drop-down list, or leave the pin alone if the right configuration is already set. If there is a pin ID in the table below that you do not see, skip it. Here are the configurations that you should have for each pin:

Pin name 	Pin ID 	Drop-down list option
Not connected 	0x12 	Not connected
Not connected 	0x13 	Not connected
Not connected 	0x14 	Internal speaker (LFE)
Not connected 	0x16 	Not connected
Internal Speaker 	0x17 	Internal speaker
Not connected 	0x18 	Not connected
Black Mic, Left side 	0x19 	Microphone
Not connected 	0x1a 	Not connected
Not connected 	0x1b 	Not connected
Not connected 	0x1d 	Not connected
Not connected 	0x1e 	Internal speaker
Black Headphone, Left side 	0x21 	Headphone

    Finally, click on "Install boot override" and then reboot. Sound should now work.
