Well I tried getting the ua-101 working under windows 7 and had similar problems. What a nightmare. Anyway, I have borrowed a freinds FA-101 and am going to try to get that to work. I have not tried to use firewire on this laptop yet so I imagine this is going to take some time...

There's a similar thread on the Ubuntu forum , also a user with a brand new notebook with the exact same USB controller and the exact same issues. Are you using Ubuntu too? Maybe it gets time to file a bugreport. I think your right. I read that other thread in the Ubuntu forum and it seems more and...

The problem is this device: Bus 001 Device 002: ID 8087:0020 It's not specified but it's a Intel Corp. Integrated Rate Matching Hub, in other words, your mobo is USB3 ready and this Rate Matching thingy also enables USB1 and USB2 devices to work with it. At least, that is what I think it is. And I ...

Your right Pablo..sorry bout that... I will view the links you posted - thanks! Jeremy - I am using a Toshiba Qosmio x500 laptop(dual boot windows 7/Ubuntu Studio 10.04) with the edirol ua-101 USB I/O. I have for a while been configuring this laptop as it is fairly new hardware and Toshiba doesn't s...

HI Pablo, I seem to have figured out the issue with xruns. I checked the checkbox for soft mode and that seems to have taken care of the xrun problem. Any idea what that actually does? Anyway it works. My problem now is that I am getting static when I try to play somthing through my edirol ua101 whe...

Hi Pablo, sorry but -p256 gives me sporadic xruns while -p128 gives continuous xruns.

I am still receiving non stop xruns

Hi! The usb bus 001 in which you have plugged your edirol is sharing IRQ number with the graphics card: Bus 001 Device 003: ID 0582:007d Roland Corp. EDIROL UA-101 16: 234 1413912 0 0 0 0 0 181 IO-APIC-fasteoi ehci_hcd:usb1, nvidia You should first try to have the EDROL in usb bus 002 which is alon...

Changing the period/buffer setting to 2 or 3 makes no difference for me.

like they say, first thing to try: just put 70 in the Priority field in Qjackctl....(this if you allready made sure that your soundcard has priority near 90, because it should havee more priority) Should I be trying to change the priority of my sound card to 82 or higher and/or my usb port (becuase...

OK so after following pablo's advice, I removed the lines I created in /etc/security/limits.conf and checked /etc/security/limits.d/audio.conf and the following is what is there: @audio - rtprio 99 @audio - memlock unlimited #@audio - nice -19 I just left it that way and rebooted for posterity, rest...

Thanks to all for the info. I will go through your suggestions when I have a moment and post my findings. Much appreciated fella's.

Just a little update. I had the same problem on the new Ubuntu 10.04, with the same "22: invalid argument" so i dug a little into it and found out that it had something to do with a bad interface setting. Although i had it on "default" it wasn't set properly, so i switched it to...
