Something is limiting playback sample rate to max. 48kHz

migo · 2026-01-25 18:55:34

Hi, I've tried to avoid resampling, searched all info about pipewire and allowing native playback but I've failed. System is up to date ArchLinux with integrated sound card.

Please use [code][/code] tags. Edit your post in this regard.

tail -n10000 /proc/asound/card*/codec#*

According to the pw-top rate is 96k on both ends, but output format in the alsa device is 48k only. Where can be the problem? Switching output sample format between 44.1k and 48k works fine, but not above 48k. Thank you.

seth · 2026-01-26 13:23:51

As mentioned, the node only supports <= 48k
Afaict only "Node 0x03 [Audio Output] wcaps 0x41d: Stereo Amp-Out" will do > 48k (whether you will hear anything over that output or it's just the volume control I can't tell)

migo · 2026-01-26 16:50:22

Understood, but this is true only for the Node 0x02, which is labeled as "Headphone Playback Volume":

Node 0x03 labeled "Speaker Playback Volume" has 192k max and I'm using internal speakers for playback.

  Power states:  D0 D1 D2 D3 EPSS
  Power: setting=D0, actual=D0

and main codec section list all sample rates:

It seem like there is a bug somewhere to me. Or I get all this wrong?
Thank you!

No.

I'm using internal speakers for playback.

Which is

The behavior of the output doesn't seem surprising - the question is whether you can utilize node 0x3 at all or that's a purely transactional device.

Thank you for explanation. Do you know the way I can try to play through node 0x3? Thank you!

seth · 2026-01-27 13:06:48

You could try to https://wiki.archlinux.org/title/WirePl … evice/node and/or https://wiki.archlinux.org/title/WirePl … e_priority to prefer that node resp. completely disable the unwanted one.
Make sure to see https://wiki.archlinux.org/title/WirePl … s_matching

Thank you, will try do it and will report back.

Hello, I still think you are wrong, according to the hdaanalyser is output set to 0x03 and changing volume slider in this property changes actual volume. You can see this here too 0x03* :

I don't know if it is enough, maybe this enumeration is done during boot by alsa and is fix. What do you think? Thank you!

I think you're speakers are "Node 0x06 [Audio Output] wcaps 0x411: Stereo" and "Node 0x03 [Audio Output] wcaps 0x41d: Stereo Amp-Out" is a transactional device.
Does the notebook advertise 24bit/192kHz output (this would likely be all over the manual and on some stickers a major marketing point)

But when I select output to "Node 0x06 [Audio Output] wcaps 0x411: Stereo" in Node 0x17 there is no audio. But when I disable all connection to the "Node 0x06 [Audio Output] wcaps 0x411: Stereo" in all widgets connected to it playback is running without interruption.

and node 0x06 is capable only playing 48k right? But output is playing 44.1k just fine.

https://pasteboard.co/sAab0xQpmWjl.png is 404 and I don't really understand what you're trying to say with this.

The stream will be upsampled.

Otherwise what makes you believe some internal notebook speakers can run 24bit/192kHz ?
192kHz is typically required for processing to avoid interpolation artifacts but gets downsampled to 44kHz or 48kHz for actual playback - I'd frankly be surprised if it was marketed for notebook speakers (and marveled how to get that fidelity out of that size/tech)
The overall support probably exists to be able to link out the signal to some external HiFi DACs

Link is working fine here...

It is not upsampled it is playing 44100, please look at output from pw-top in my previous post.

I'm aware that this doesn't have real sense for internal speakers, but for headphone use it have.

Yes laptop is Hi-Res certification (for headphone), please look:
