Rode Podcaster

[kyle_1974]

I've noticed after a reboot, it has gone back to like HWPro rather than having the ,0 bit (does that make sense?)

That's surprising but shouldn't make a difference I think.

For USB cards, on the Settings->Parameters tab, I've heard people recommend setting 'periods/buffer' to '3'. That will increase latency a bit, but that might not be a problem since you're likely not doing live overdubs anyway.

Ok, Jack will start now having changed the buffer to 3, but there are now thousands of xrun errors, which is how I first (virtually!) met lad when he managed to fix them.

[merlyn]

Did you hear Xruns? I notice QjackCtl reports 0 (449). When I used QjackCtl I remember that I didn't hear the Xruns in brackets -- I did hear the Xruns not in brackets. If you can't hear them it's not such a problem.

This new kernel you've got could be a stock kernel, so you could try using the threadirqs kernel parameter.

[kyle_1974]

Ah that's interesting... I think I did hear them under the old system and I mentioned Lad helped fix those - but I could hear 1/2 per a show but this time there were no indicators for that - I will test it now!

In terms of the kernel, I will definitely one of you to tell me what I am doing! I kind of stumbled into all this - not a muso at all!

[merlyn]

To see if you have threadirqs loaded use

Code: Select all

$ cat /proc/cmdline | grep threadirqs

If that returns anything you do. If it returns nothing you don't.

I think I do?

You do indeed. Now you can raise the priority of your soundcard using rtirq. I think the configuration file is in /etc/default/ on Ubuntu. Adding 'xhci' to the rtirq name list has worked for other people like so :

Code: Select all

RTIRQ_NAME_LIST="xhci"

Thank you - I have found the config - do I comment out the bit that is there already?

Code: Select all

# IRQ thread service names
# (space separated list, from higher to lower priority).
# RTIRQ_NAME_LIST="rtc snd usb i8042" # old
RTIRQ_NAME_LIST="snd usb i8042"

That's a good idea so you can revert it. It would end up looking like this :

Code: Select all

# IRQ thread service names
# (space separated list, from higher to lower priority).
# RTIRQ_NAME_LIST="rtc snd usb i8042" # old
# RTIRQ_NAME_LIST="snd usb i8042"
RTIRQ_NAME_LIST="xhci"

Then try

Code: Select all

$ rtirq status
$ sudo rtirq restart
$ rtirq status

and you should see the change. Hopefully that will reduce Xruns.

Hiya

Have made the first change but the second set just says "command not found"?

[merlyn]

OK. Must be in a different place on Ubuntu. Try using this path :

Code: Select all

$ /etc/init.d/rtirq status

If that works use the same path for 'restart'.

That seems to be working now thank you! I will try and start the Rode again!

[kyle_1974]

Ok, update. Which is weird.

So after changing that RTIRQ, still getting thousands of XRun errors in the rec bracket. So far only one on the non bracket bit.

Device is seen in audacity and can record.

Device is seen in Jack.

Sound is not going back into Rode from IDJC. It's a USB connection and in Pulseaudio hardware config, it's set to the Rode in and out and the same on the Pulseaudio "usual" volume control.

So I am stuck now I think, I still have a few days to return to Amazon. But inspiration is failing me at this point - unless I start doing the radio through the Mac or Windows - which I really really don't want to do

EDIT: So now after disabling PC soundcard, I have got music going back to the Rode but it is very scratchy and distorted and you can't make anything out, but at least something is going back.

FURTHER EDIT: Had a mad idea which is how lad got into helping me!

So chain is:

Rode into JACK/PC as HW Device

Rode mics and input records to internal card, bluetooth works, everything. Processing is turned off on Rode as my dbx is taking the strain. No more noisy pots on old behringer mixer.

Output in Jack is internal normal sound card. Headphones into PC.

No X run errors.

This way mix of music/talking is recorded in IDJC. Clean mics recorded internally in Rode for editing.

This is the way my old PC was set up to record which we could never replicate hence using In/Out on Jack on the same device (which I know is the way it is supposed to work) and why I washed up here in the first place - though I am glad I did!

The only issue I had with Behringer was when we were using In/Out in Jack to the mixer and I had no end of trouble that way - so I think it is all fixed! (Not sure how it works, it just kind of does. Thank you though all!!!)

Sidenote - I could literally cry with joy at this point! And if I ever use the dual in/out, listening with headphones into the Rode on the Mac, I know that works as well for when I am out on the road!

[kyle_1974]

Sorry for the bump - just wanted to provide an update.

Well, not much of an update. I have been getting lots of help from Rode about working out how to properly use the Podcaster but I've had to go back into Windows/Mac (which pains me) but I still cannot get Linux to work with it.

Using the latest 5.xx kernel still at least sees the device and names it but no joy in it being of any actual use. Sigh.
