Audio Skipping on GoXLR

I get audio skipping when using a GoXLR on Arch. I don't get any skipping if I use my built-in sound card or a different USB DAC such as the Dragonfly Cobalt. I tried a few things with PulseAudio such as decreasing the nice level to -15, enabling realtime audio (and using the linux-zen kernel), setting different buffer sizes and sample rates, and setting tsched=0 but nothing worked. I found this thread and tried

aplay -Dplughw:2 test.wav

and the audio still skips.

Re: Audio Skipping on GoXLR

Have you tried Jack?
If I remember right Pulse isn't recommended for low latency applications.

Re: Audio Skipping on GoXLR

I disabled PulseAudio and tried Jack and got the same audio stuttering. I again went through different combinations of Frames/Periods but there was no difference in the stuttering based on those settings.

Re: Audio Skipping on GoXLR

If aplay -Dhw:2,0 stutters then all implementations that sit on top of it will usually stutter as well.

Maybe try and disable usb auto suspension and can you post a

sudo lsusb -vd 21b4:0085

Re: Audio Skipping on GoXLR

I disabled USB autosuspend by adding

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"

in my /etc/default/grub (and regenerated grub config) and am still getting the stuttering.

sudo lsusb -vd 21b4:0085

prints nothing and exits with code 1.

Re: Audio Skipping on GoXLR

Hmm weird I took those from the pulse outputs, check the direct output of lsusb and pass the vendorId:productId of the dragonfly (are there multiple different ones?)

Re: Audio Skipping on GoXLR

Oh, my bad. I assumed that was for the GoXLR so I didn't have the Dragonfly plugged in when I ran the command. With the Dragonfly plugged in I get
