I’m running wfview on Ubuntu 20.04.4 and i’m getting intermittent audio. It’s best described as oscillating, choppy or fluttering, where it is on and off several times a second.
So far i’ve tried:
- connecting the Ubuntu laptop and 705 to my Wi-Fi router: problem exists
- connecting the Ubuntu laptop directly to the 705 access point: problem exists
- wfview on a Mac via my Wi-Fi router: works without issue
By deduction the 705 and wireless config is fine and the laptop is a high spec, 2021 purchase running a fresh install on Ubuntu. Hardware utilisation is negligible. So i think it is something Ubuntu specific.
I do have to run wfview153 to avoid the segmentation fault, if that’s relevant.
Can you post the first line from your /tmp/wfview.log file please as that contains various info regarding your environment?
I have not been able to reproduce this particular issue but I know a couple of other users (including Elliott) are experiencing this pulsing audio it can usually be (temporarily) cleared by moving the RX latency slider (which causes audio to be restarted.)
I am hoping to replicate the environment of a user with this issue so that I can try to find what is causing it. I suspect it may be a bug in earlier versions of Qt (which wfview relies heavily on).

It’s also worth checking that you are on the latest version, there have been a few updates to master over the last couple of days which could impact this issue.

Top of log here:

I also tried increasing the RX latency, which had an effect. The real-time latency was up to 25ms but the slider needed to be set to 200ms to remove the flutter completely. Is this a credible workaround?
Trying the latest version now
