 Posted: Sun May 02, 2021 7:32 am Post subject: HP laptop with B&O Play - Sound is weak and thin |
 |
|
| Pavilion 15-ab121dx. Sound works, but compared to its days as a windows machine, the quality is absolutely pathetic. Weak, thin, no low end to speak of. Have I missed something in the configuration, or is it just something I'll have to get used to? Everything I've found so far suggests that getting B&O Play to work well with Linux is not an easy matter. |

Hi.
Please post your
Also do you use pulseaudio/pipewire or pure alsa?

DarkAudit,
Does the sound play too fast/slow too?
If the source is 7:1 or any more than stereo, its easy to play the wrong channels into a stereo output.

No. It just sounds very thin. By comparison, playing the same YT video as a windows machine has a lot more oomph to it. |

You have two sound cards. Pulseaudio is a wrapper around alsa.

That first one is for HDMI or DisplayPort output. I'm having issues with the quality of the onboard speakers. |

DarkAudit,
Not all digital audio is equal. CDs use a sampling rate of 44.1kHz and videos use 48kHz.
If you need to do sample rate conversion and don't, it sounds really horrible.
Can you test with sources that use both sample rates please?
A CD rip and DVD rip will do nicely.
Also post the content of /proc/asound/devices.
If you have a /etc/asound.conf file, post that too.
As pulse is a wrapper, it can't work until alsa does. My approach to this is to rip out pulseaudio, fix alsa, then if you want to, put back pulse.
Be aware that this will break things that must have pulse, like firefox-bin.
As I'm not a pulseaudio user, I have no idea how to address this any other way but I'm sure someone else will be along in a wee while.

First I want to make sure we're on the same page with my issue.
Take your typical YouTube video. Yesterday's Lockpicking Lawyer post, for example. The sound works from both speakers, but there's just no real low end. Like a cheap transistor radio. It's not distorted or anything, just weak and lifeless.
I don't have any of my headphones or earbuds with me at present, but I have to head out anyway soon and can grab them to test that side of things. |

DarkAudit,
If headphones or earbuds fix it, there is something wrong with your speakers or the output amplifier in the laptop.
You can test that by booting into another operating system that provides sound output.

Headphones sound great. Tested with Chase by Giorgio Moroder. 
I guess it's still an unresolved issue for the onboard B&O speakers. |

DarkAudit,
There is a kernel bug and a fix.
I don't know if it got into the kernel.
Alsa is not very good at detecting CODEC wiring, so you may need to pass module parameters when snd-hda-intel loads.
There is a list at /usr/src/linux/Documentation/sound/hd-audio/models.rst.
Trialling module parameters is best done with the code built as a loadable module.
