OvenWerkszequence: Re: 3.8, it also doesn't look like 3.9/10 will fix this from the converstion on LAU15:08
smartboyhwOvenWerks, uh oh...;15:08
smartboyhwThis can be pulled I think sometime.15:09
smartboyhws/This/This patch/15:09
kubotusmartboyhw meant: "This patch can be pulled I think sometime."15:09
OvenWerksI need to get out my USB IF and see if I have similar problems... though mine is only a USB 1.1 audio device.15:10
smartboyhwOvenWerks, uh. 1.1...15:10
* smartboyhw isn't sure if he has a 1.1 deice.15:10
zequencemost usb devices run in 1.1 mode on Linux15:11
zequenceaudio devices, that is15:11
OvenWerksUSB 2.0 devices were problematic in my price range15:11
OvenWerksIf I was to buy one today, there are better choices15:19
smartboyhwHmm, something was wrong with my sasl...15:19
smartboyhwGrr, the auth timed out,.15:20
OvenWerkstons of xruns.15:23
smartboyhwzequence, ..........15:23
OvenWerkslots of midi errors... but midi is from a PCI card15:23
* smartboyhw really wants USB 3.0 ports and drives.15:23
OvenWerksUSB 3.0 will not really help audio15:24
smartboyhwOvenWerks, I want drives.15:24
smartboyhwOvenWerks, really? 15:24
OvenWerksThe only way it might help is to allow some kind of extrenal hub15:25
OvenWerksRight now thge audio IF needs to be the only USB device on a USB port adding anything else (mouse KB etc) will cause problems15:26
OvenWerksa page of errors at shutdown as well, That never used to happen. Even at -p1024 with no xruns15:29
OvenWerksp256 is still ok15:30
OvenWerksp128 is over the line, lots of xruns15:32
OvenWerkseven raising periods to 3 doesn't help.15:33
OvenWerksp256 at 10ms is ok for recording, but not so good for live use like softsynth/effects15:36
OvenWerksI had this device stable at -p64 before.15:38
