@net147 well it installed and I seem to have sound. no way of doing the loop back test though. I'll keep you posted. And sorry for late reply :(

@funkmuscle I have restored the MAX_URBS/SYNC_URBS parameters to default so it should work with more interfaces and modified the module to allow specifying custom parameter values as module options. This will let you tune the parameters without having to rebuild the package. Instructions are displayed when the package is installed/updated.

@funkmuscle It is not necessary to update GRUB after installing.

hey net147, I am using Focusrite 2i2

I also update grub after installing. That step necessary? Like I've said, I've using Ardour and Linux for over a decade, almost 2 but had to stop learning Unix/Linux a while back but still always using Linux and Arch for that long. So please forgive my sometimes dumb questions

If you are having trouble getting audio to work with this patch, try increasing MAX_URBS in lowlatency.patch to 3 or 4 on line 13, then run updpkgsums and makepkg -Cifs.

@funkmuscle Which USB audio interface are you using?

funkmuscle commented on 2018-08-22 14:25

@net147, yep. been using Arch for more than a decade. I just reinstalled jack2 along with realtime-privileges and the rt-lts again and system is back to normal. didn't install snd-usb-audio-lowlatency-dkms.

@funkmuscle What audio hardware are you using? Did you follow the Arch wiki pages for Professional Audio such as adding your user to audio group, configuring RT limits, etc.?

funkmuscle commented on 2018-08-22 13:53

@net147 just uninstalled it and Jack2 runs fine. It also changed my setup too as now I getting memory issues. this error now with Ardour and MixBus:

WARNING: Your system has a limit for maximum amount of locked memory. This might cause Ardour to run out of memory before your system runs out of memory.

You can view the memory limit with 'ulimit -l', and it is normally controlled by /etc/security/limits.conf

this was taken care of when first setting up.. will downgrade rt kernel to see if that was the or is issue

@funkmuscle Do these issues occur if you start up the RT kernel without this package installed?
