Hello,
I have 2 soundcards:
% cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7e00000 irq 42
1 [Pro ]: USB-Audio - FastTrack Pro
M-Audio FastTrack Pro at usb-0000:00:1d.0-1.1,
full speed
I run jackd on the second one of course.
When starting puredata, even if I don't set it up to use JACK, I get
this error in dmesg:
hda-intel: IRQ timing workaround is activated for card #0. Suggest a
bigger bdl_pos_adj.
---
Jackd, on its side, produces very frequent and regular xruns. I close
puredata, and xruns continue to occur:

When I disable snd-hda-intel, I seem to be able to run jackd & puredata
without trouble.
Other audio apps don't produce such results, but I guess puredata makes
some tests at startup which produce this issue.
I'm unsure where to address this issue, but hope this report can be
useful in some way, so if anyone has clues about where to investigate ...
Cheers,
01
