Re: Ultralite AVB

Stanlea, the channel hopping seems to be the only issue. Audio plays cleanly through some channel for some time (sometimes seconds, sometimes minutes), and then hops over to a different one. Sometimes that hopping takes a few seconds, during which audio fades crunchily on the channel it's leaving, b...

Re: Ultralite AVB

Unfortunately, it's still not working. I've compiled my realtime kernel with the patches (formerly it wasn't a realtime kernel, but I've figured that out!) I've opened my MOTU interface with 3 periods, and a realtime priority of 0 or 40, and your script doesn't seem to fix the channel hopping. I've ...

Re: Ultralite AVB

After trying it again last night, the channel jumping has returned. I thought it was an issue of the priority value on my DAW being set too high, since lowering it appeared to fix the issue earlier. Not sure what changed since then. I'm afraid I'm a little new to this; how do I query or modify the p...

Re: Audio jumping between channels on a MOTU 16A

Stanlea, I've not done substantial testing yet; I just got it stable yesterday and plan to do more soon, hopefully this evening. I jumpered two outputs to inputs so that I could concurrently test 3 outs and 2 ins with one audio stream, and it worked very well for about an hour, continuously. No inte...

Re: Audio jumping between channels on a MOTU 16A

Stanlea, I have been using the web interface to do routing, mixing, and configuration, and confirmed that the host and device agree on sample rate, channel count, etc. It's a pretty cool interface! I've recently gotten the audio to stabilize, albeit on channels other than the specified ones, but it'...

Re: Ultralite AVB

Drumfix, thanks for the advice about thread priority! I've made my audio output apparently stable by just reducing the realtime priority of the host thread. I think the priority of those other threads was set properly (thankfully, as I'm not sure how to change it), and I just needed to decrease the ...

Re: Ultralite AVB

I started another thread a few days ago, but it might be worth jumping in here as somebody who has applied these patches and still gets channels jumping around. I'm on Manjaro, kernel version 4.19.16, trying to get a MOTU 16A to work. The patches seem to make the audio less crunchy, and maybe make t...

Re: Audio jumping between channels on a MOTU 16A

https://www.linuxmusicians.com/viewtopic.php?f=6&t=18046&start=135 I've successfully patched, recompiled, and installed my kernel! Sorry for the delay, it took some time to figure this out. Thanks for providing this patch; it seems to solve the crunchy audio issue. However, audio will still...

Audio jumping between channels on a MOTU 16A

Hi LinuxMusicians, Hopefully this is the right place to ask this question; feel free to redirect me if not. I've recently put together a computer partly for the purpose of doing some audio work, hoping that I could use my existing MOTU 16A for conversion. The 16A is class compliant, and I thought th...
