Pops/clicks on audio interface

[mvanorder]

I have a Behringer UMC204HD which works fine on my work laptop, but when using it with my personal laptop it clicks and pops while audio is playing. This doesn’t happen using the thinkpad’s built in audio or on bluetooth, and doesn’t change whether I use pulseaudio or jackd. It also doesn’t change with increasing or decreasing sample rate, frames/period, or periods/buffer.

Here’s the pulseaudio sinks and sources

Hello @mvanorder

Maybe the same issue like here?

Loud plopping via USB-Audiointerface, sometimes disconnecting

Hello @HansD Checkout /etc/tlp.conf: # Enable audio power saving for Intel HDA, AC97 devices (timeout in secs). # A value of 0 disables, >=1 enables power saving (recommended: 1). # Default: 0 (AC), 1 (BAT) #SOUND_POWER_SAVE_ON_AC=0 #SOUND_POWER_SAVE_ON_BAT=1 I assume it happens only in Battery mode? Check also if tlp is running: systemctl status tlp Ubuntu seems to not use tlp then for powersaving.

Mine sounds like xruns, but jack isn’t logging xruns(when I’m using jack), and the normal steps to fix xruns isn’t affecting it.

I have a similar Problem with a Steinberg UR22 Interface on Ubuntu. The interface used to work on earlier Versions, so this seems like a regression possibly in the Kernel.

I’m apparently not allowed to post links here, but you can find my Question on askubuntu via my username.

[nikgnomic]

The Behringer interface is marked as the default sink for 4.0 surround sound playback in PulseAudio

2 sink(s) available.
  * index: 0
	name: <alsa_output.usb-BEHRINGER_UMC204HD_192k-00.analog-surround-40>

    sample spec: s16le 4ch 44100Hz
	channel map: front-left,front-right,rear-left,rear-right
	             Surround 4.0

Is there a PulseAudio profile available for Analog Stereo Output ?

The interface may not be detected correctly in PulseAudio for surround sound playback.
(not many hardware interfaces have a custom profile in /usr/share/alsa-card-profile/mixer/profile-sets/)

It may help to reduce pops/clicks by increasing the setting for resampling in /etc/pulse/daemon.conf
the default is usually not very good quality
; resample-method = speex-float-1
but it usually only needs a small increase
resample-method = speex-float-3
