Realtek HD Audio Device not detected

Output of lspci only shows Intel HDA which is on-board integrated sound card not the dedicated one. The dedicated sound card is Realtek HD Audio (ALC282).

Re: Realtek HD Audio Device not detected

Intel HDA is also the driver used for lots of sound chipsets under linux.

please post 

$ lspci -nnk

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Re: Realtek HD Audio Device not detected

Realtek chipsets all are part of the HDA standard and are usually all implemented onboard, what makes you think that the card you're seeing isn't just that? More of interest would be the codec which will likely point to some realtek device, what's your output of 

dmesg | grep snd

dmesg | grep snd

Actually the sound output from laptop speaker lacks dynamic range and bass and sounds like low bit-rate mono which made me think the realtek chipset is not being utilized. Output of dmesg | grep snd :

Re: Realtek HD Audio Device not detected

So the card is there and detected, whether it has bass or plays to more channels or whatever depends entirely on your configuration. If you haven't configured anything else you will get a simple stereo channel mix. Do you use pulseaudio? If you do you might want to post 

pacmd list-cards
pacmd list-sinks
amixer -c0 #Post that one regardless of whether using pulse or not there might be some setting switches to flip, needs alsa-utils

Re: Realtek HD Audio Device not detected

So no stereo surround profiles or any other setting in that regard in the mixer channels. So from a hardware POV there's not much more you can do here.

One thing I suggest you do either way, is to up the resampler quality used in /etc/pulse/daemon.conf from the conservative default of speex-float-1 to some higher quality like speex-float-5 , which will help if your input source is to be resampled.

If you are generally unhappy with your sound you'd have to apply some form of software wide equalizer, pulseaudio provides quite a few possibilities for this. A very extensive example with a lot of options and possibilities is the pulseeffects package, which provides you with a nice GUI where you can mix and match relevant filters until you find something that sounds good, and then you can switch your applications to play back from the sink created by pulseeffects

Thanks for these suggestions, it improved the audio quality and now I have something to start with to tweak audio settings.

Re: Realtek HD Audio Device not detected

It looks like this is an HP laptop. If it has Bang&Olufsen speakers, then it may be a similar issue to this: https://bugzilla.kernel.org/show_bug.cgi?id=189331

Thanks, you guessed right, it's HP notebook with B&O speakers.
