Sorry gang, I know I'm bumping this 3 years later, but there still doesn't seem to be a solution here or anywhere else I can find, but I have hit on the right track for anyone still trying to get this working. HDA Jack retasking was mentioned and dismissed early on in this thread but has gotten me halfway there, I still have to fiddle with the large assortment of pin settings to get the rest.
The issue is the same as a gaming mouse, B&O uses a 4 speaker setup with the front 2 speakers controlled by a power amp, but just like a gaming mouse only mapping the 3 standard buttons by default (and you have to manually task the rest), only the rear 2 speakers are enabled by default, the front 2 and the amp have to be manually set. It is the most badass sound I've ever had in a laptop, but without the amp it's as tinny as any other cheap on-board audio out there.
HP Envy 17t, Ubuntu Mate 20.01.1 LTS, and the soundcard reports back with 4 pins in use by default:
0x12 (Internal Mic),
0x14 (Internal Speaker),
0x15 (Black Headphone, Right Side),
0x1a (Black Mic, Right side)
Selected Realtek ALC3241 and checked "Show unconnected pins," and 0x1d, 0x19, and 0x13 only list Internal Mic for an override option, 0x1e only has SPDIF (which my specific soundcard doesn't have a jack for), and that leaves 0x16, 0x17, 0x18, and 0x1b with a full assortment of override choices.
After a little trial and error, I set the override for 0x16 to "Internal speaker (LFE)" and now the right front speaker and the amp are both working... just not the left front speaker.
I ran into a number of issues getting there, possibly due to not having strong scripting skills, that someone else may be able to work around more easily. Applying the changes came back with a
tee: /sys/class/sound/hwC0D0/reconfig: Device or resource busy
Tried to manually kill pulseaudio and in the terminal got "permission denied" even as SU. Used Mate's System Monitor gui instead to kill it was successful for 2 seconds, then it relaunched immediately, and crashed everything. What I found was I could ignore the "resource busy" message, I just had to log out after getting that message (not reboot), then log back in and the changes were applied.
For anyone looking to dig deeper for the why's and how's for a cleaner solution, originally fuser only reported back:
/dev/snd/controlC0: [user] 9377 F.... pulseaudio
After finding an override that partially worked, fuser now reports back:
Code:
/dev/snd/controlC0: [user] 8477 F.... mate-settings-d
[user] 9377 F.... pulseaudio
/dev/snd/pcmC0D0p: [user] 9377 F...m pulseaudio
I haven't delved into any changes made to any of the conf files, I'm just satisfied with the results, but hopefully this can help someone else with this issue, or someone who can actually code to come up with something to make the process easier.
