[linux-audio-user] via82xx and jackd

Hi, 1) I'm using alsa 1.0.1 with the latest version of jackd on a via kt400 mobo (VT8377) and a VT8233 audio controller. I have the low-latency/premp kernel patches as well as the capabilities patch applied to a 2.4.22 kernel. I get xruns like crazy that average around 0.09 msecs when running jackd in duplex mode. These disapear when running in either capture or playback mode. I had seen that there may be some issues with the via82xx chipset and jackd on the alsa list, but no solutions or description of what the actual problems were. Am I stuck in a duplex-free zone or is there a way to work around this? Will this affect my ability to use ardour as multitracking device using the mic/line-in, or will it only cripple my ability to use other programs as jack slaves? 2) Even with the capabilities patch, I get the following error when running jack as a normal user: JACK: unable to mlock() port buffers: Operation not permitted cannot set thread to real-time priority (FIFO/20) (1: Operation not permitted) cannot use real-time scheduling (FIFO/10) (1: Operation not permitted) Any ideas? Thanks! Keith
