How to Enable High Definition (HD) Audio in Fedora 35?

[yosenheim]

Before I upgraded to the Kernel 5.16.14, I was able to play HD Audio in my Fedora 35 Workstation by making a few tweaks in the ‘pipewire.conf’ file located in “/usr/share/pipewire”. I just removed the ‘#’ marks and uncommented the PCM settings section in the said file. After a reboot my DAC would display 32 bit 384000 hz sample rate. Unfortunately, after the latest update dropped, the same method does not seem to be working. On the contrary, If I try to enable HD Audio, the sound system does not even detect any audio devices and stops working altogether.

Can anyone help?

/usr/share/pipewire

This is the wrong place to edit. Please read the top of the file:

# Daemon config file for PipeWire version "0.3.48" #
#
# Copy and edit this file in /etc/pipewire for system-wide changes
# or in ~/.config/pipewire for local changes.
#
# It is also possible to place a file with an updated section in
# /etc/pipewire/pipewire.conf.d/ for system-wide changes or in
# ~/.config/pipewire/pipewire.conf.d/ for local changes.
#

The update did overwrite your changes in /usr/share/pipewire

It does not work. Have tried that. I uncommented this in the pipewire.conf file.

{ factory = adapter
    args = {
        factory.name           = api.alsa.pcm.source
        node.name              = "alsa-source"
        node.description       = "PCM Source"
        media.class            = "Audio/Source"
        api.alsa.path          = "hw:0"
        api.alsa.period-size   = 1024
        api.alsa.headroom      = 0
        api.alsa.disable-mmap  = false
        api.alsa.disable-batch = false
        audio.format           = "S32LE"
        audio.rate             = 384000
        audio.channels         = 2
        audio.position         = "FL,FR"
    }
}

It worked before but not anymore. If only there was a guide or manual on how to do it. Setting up High Resolution Audio in PulseAudio is kind of easy when compared to pipewire.

Hi, you could try also adding default.clock.allowed-rates = .... From pipewire.conf on top line find part context.properties = { then inside it find part #default.clock.allowed-rates = [ 48000 ]. Change it to:

context.properties = {
    ...
    default.clock.allowed-rates = [ 48000 384000 ]
    ...
}

After that restart pipewire and wireplumber.

hey, this worked for me. Copied the ‘pipewire.conf’ file to ‘/etc/pipewire/’ , then added, ‘default.clock.rate = 384000’ into the ‘context.properties’ like this,

context.properties = {
…
default.clock.rate = 384000
…
}

Logged out and logged in. Now, it is working again. Thanks a bunch for the idea @oprizal

I use strawberry, direct output to soundcard via ALSA, direct play in usb DAC/DAP player with the same bitrate and bitdepth on the file audio, this player doesn’t do resampling. output from strawberry directly transfer to ALSA kernel driver.
