[App_rpt-users] Motor boating

[Steve Gladden]

I was told (off list) awhile back that with using XIPAR I should expect NOT to have the issue.
I've not taken the time yet to try it out.
Pretty sad as I'm one of the main mentoners on this list about the USB audio performance not being quite perfect. :)

I'm actually hoping to get a better hands-on understanding on what exactly *is* causing it.
And if it's really fixable or not.

I am dead set on NOT using USB for any type of production/commercial system and only because of this particular issue.
Which really is OK but I'm ever and constantly curious WHAT causes it.. and how the USB / audio subsystems all work and what can possibly
Be 'interrupting' the audio write to the usb device routine. Is the linux usb audio subsystem being used really that weak etc. etc.. or is it a DAHDI problem blahblah ..
Sorry VERY non-technical :)

I tried the URIx and same issue occurred, so I don't think it is really an issue with the URI
Not sure what the issue is, but I am going to try the XIPAR package just to see if anything changes as they run on Fedora. I'll report back, likely after the hurricane passes this weekend as I will be very busy.
This only happens on any one of my 8 PC's that contain an ASUS motherboard. I have gone to much older and slower machines (even down to 400 Mhz) and it works just find on them. Go figure.

Anybody come up with a solution to the motorboating problem?  I was following the posts last month with interest but I don't think there was a solution to the problem.  I had this problem a few months ago using the URI (Version 1) on an HP DL320 (USB 2) server and figured it was a computer issue so I did a fresh install on a HP ZE4101 (USB 1) laptop that is atleast 8 years old.  Only the URI is the common hardware piece.  It was suggested yesterday perhaps the URI is the culprit but it seems to function otherwise and with several reports of others having this same problem I dont think I would blame the URI.

are only people using URIs having this problem?  are people using fobs experincing this?

Any ideas?
