Last night I cranked up Jack and started Ardour and opened six mono channels and would let it run for 15 - 20 mins several times without a single xrun. Then it got to be about ... oh 1:00 am. I didn't introduce Jamin last night but I will tonight. I'm on a modem at home so I had to bring my PC into work today to download the lastest updates from the CCRMA site. I also agree with you that I really don't want a single xrun. I have a recording session coming up this weekend and I'm *REALLY* happy I moved to FC1. I built temporary walls stuffed with insulation that transformed the kitchen into studio "A", the dining room into studio "B" and the living room is now studio "C". The laundry room is the control room .. :-)) Brad. ----- Original Message ----- From: "R Parker" <rtp405@xxxxxxxxx> To: "A list for linux audio users" <linux-audio-user@xxxxxxxxxxxxxxxxxx> Sent: Tuesday, September 28, 2004 10:40 AM Subject: Re: [linux-audio-user] Is everyone sick of interrupts yet? > Hi Brad, > > > > > I'm getting 5.8 msec latency in JACK with 128 > > frames/period at 44100 and > > > > 2 periods/buffer.
