A reboot seems to have fixed it for me while keeping the settings at 'OutputDeviceName=sysdefault'

I can now play audio everywhere fine, and I no longer get the brief loud white noise when I start up Lightworks. Solved two problems at once!

I did not reboot before because it's very rare that I ever reboot unless I get kernel updates... Cheers.

I've already done it for you. In future if you need to do it again, you just edit your first post and change the title.

thanks for changing the topic. I checked the log and Lightworks is using ALSA that is why no pulseaudio application can access to the sound hardware. So must be my system I guess. The weird thing is that 14.6 worked just fine.

the buzz sound and some audio connection weirdness seem to be new features on linux.

got the same buzz here...

did you check to which audio device you connect? lightworks can connect to alsa, pulseaudio , jack, etc...


Would you share how to set up jack for Lightworks? Can it work with a Jack patch field app? If you could start a new thread for this I would be grateful. Having trouble getting it to work running ASIO for ALL drivers.

I made some tests, 2years ago on Windows 7, with ASIO4All and another ASIO driver. Based on that, I would think that Lightworks isn't prepared to work with any kind of low latency driver, ASIO included. It needs an audio device with highly relaxed buffering characteristics for stable operations Furthermore, rewiring the ASIO drivers to the default Windows sound device, which is what Lightworks needs, caused all sorts of trouble with other applications. I didn't use Jack, but VB-Audio Hi-Fi Cable, though.
It's better to travel well than to arrive...

ASIO4ALL works fine under Win 10 for all the apps I use that require it as well as my Shure preamp and Black Magic Intensity Pro.
Specifically I'm trying to connect Lightworks to Harrison Mixbus for audio sweetening.

@David Rasberry

sorry for the late answer,

I use jack on linux to route all my audio through. So with cadence I route sources that connect to pulseaudio or alsa into jack and use jack to output everything to the sound card.

I use Harrison Mixbus as well for audio editing, but I do not run them together connected. I export from lightworks (aaf or stems for example) and import into Mixbus (with aatranslator software for converting aaf to ardour file format, there are other ways too... )

This is the best way of roundtripping i found.
