I'm using Ubuntu 22.04
on my Razer Blade 14 (2022)
laptop. When external speakers are connected through the audio jack I get this constant, loud noise that is present all the time, no matter how loud I set my system volume and no matter which audio output I set in the system settings.
(For example, if I set the audio output to be laptop speakers: I get normal sound from the laptop speakers + noise from the external speakers.)
Here are some observations:
- When I boot
Windows
on this machine, the audio jack works just fine. However, the noise is present when I turn off the machine with the audio jack connected.
- The noise changes a bit when I unplug the power, but is still present. (Power adds high frequency noise to the already present low frequency hum.)
- The noise is present when I disable the
pulseaudio.service
and pulseaudio.socket
- The noise is present when I change the power settings in the GUI (
Power Mode
, Power Saving Options
)
- If I switch to the audio jack output, nothing is being played there, I can't hear anything through the noise no matter the loudness of the speakers (Which I tweak through and external knob for speakers volume)
- The output
Headphones - Family 17h (Models 10h - 1fh) HD Audio Controller
is present when the speakers are plugged in the audio jack.

Note: I boot from an external SSD through a USB-to-SATA connector. This particular OS wasn't initially installed on the Razer machine. I initially installed it on another desktop machine. Right now I can't use that machine but I need the environment I created on the disk for my work, so I just took out the SSD and plugged it into my laptop. Doing a fresh install is not an option for now.
