Choppy sound recording a guitar using Mint 18.3 and a Line6 Pod X3 Live – Kernel issues? [on hold]












-2















PC specs are A8-7600 CPU, 16GB RAM, 128GB SSD boot drive and 1TB SSD data drive. I have a Line6 Pod X3 Live, which is a combo guitar effects pedal and USB audio interface.



Under Mint 18.3 and standard kernel I get tiny but frequent drops, as if the PC can’t keep up.



I can install this in Windows 7 and I can record my "playing" into Audacity without any drops, so I’m happy that the pedal, software and the PC are up to the job.



My first, and so far only, idea is to install a lowlatency kernel.



1) I ran sudo apt-get install linux-lowlatency which installed kernel 4.4.xxx-lowlatency (which is quite a bit older than the standard 4.15.xxx-generic).



Audacity doesn’t show the X3 as input or output. I ran lsmod which showed that snd_usb_line6 and snd_usb_podhd were not loaded. I modprobed them in, but no change.



2) I installed Ubuntu Studio to a spare disk. It has a 4.18.xxx-lowlatency kernel and both modules were installed.



My wireless mouse and keyboard were unusably slow, so I swapped those for wired versions. Audacity recognised the X3, but recording was completely garbled.



Grief-stricken, I sobbed myself into a fitful sleep.



Is this a kernel problem or a module problem? Advice welcome, and thanks for reading.
