Hi Remmy,
I think I've seen the exact same issue on the SuperCollider list (but I
don't have time to search for it). The problem is that the sound card
uses a fixed(!) non-power-of-2 hardware buffer size. (Who thought this
was a good idea!?)
I tried pd -jack in terminal and there's a "Partial read" message
constantly appearing. With callbacks the message turn into "jack:
nframes 1008 not a multiple of blocksize 64"
Both messages essentially mean the same thing: Pd expects the number of
audio samples coming from the hardware to be a multiple of 64. Pd
*could* support non-power-of-2 buffer sizes in the future (you might
file a feature request on GitHub), but in the short run, use another
sound card ;-)

Hi,
got a new dell 13 5301. It comes with a sof-hda-dsp card. After
installing Ubuntu 20.04, Qjackctl was not working. I found a solution
here:

Qjackctl started fine with sr 48000 and period 1008 and I have clean
sound from vlc, audacity, ardour, etc but Pd 0.50.2 is constantly
crackling.

Then I tried pd -jack -blocksize 252 (also 504, 1008) but the problem
continues. Probably I'm missing something, so any help to fix this
will be appreciated.
best, rc.
