JACK to OSS4 issues...

Hello! I finally got a system running 64 Studio with my LynxONE soundcard, which only supports OSS. It's a proprietary driver. The driver works, as osstest reveals. However, after setting all my system and app preferences for OSS, JACK still fails to start. 2:54:25.715 Patchbay deactivated. 12:54:25.769 Statistics reset. 12:54:25.786 Startup script... 12:54:25.787 artsshell -q terminate Cannot connect to server socket err = No such file or directory Cannot connect to server socket jack server is not running or cannot be started Cannot connect to server socket err = No such file or directory Cannot connect to server socket jack server is not running or cannot be started Creating link /root/.kde/socket-64studio. Created link from "/root/.kde/socket-64studio" to "/tmp/ksocket-root" 12:54:26.223 Startup script terminated with exit status=256. 12:54:26.223 JACK is starting... 12:54:26.224 /usr/bin/jackd -R -doss -r48000 -p512 -n2 -w16 -C/dev/dsp1 -P/dev/dsp0 -i2 -o2 jackdmp: unknown driver 'oss' 12:54:26.230 JACK was started with PID=4338. 12:54:26.232 JACK was stopped with exit status=1. 12:54:26.232 Post-shutdown script... 12:54:26.232 killall jackd jackd: no process killed 12:54:26.639 Post-shutdown script terminated with exit status=256. 12:54:28.469 Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info. Cannot connect to server socket err = No such file or directory Cannot connect to server socket jack server is not running or cannot be started It looks like jack doesn't see the oss driver? Hmm. Does anyone have any suggestions as to where to start troubleshooting this? I'm not seeing anything similar on the forums... Thanks!

Well, I compiled the latest

Well, I compiled the latest Jack 1.9.2 locally, and it still failed, with the same error messages. I haven't tried purging Jack first, as doing so apparently removes packages for half the distro... Is there a reasonably manageable way to accomplish this? Another question: OSS doesn't support MIDI. Is it feasible to run alsasequencer/etc simply to handle MIDI, while another set of drivers handles hardware and audio?

OSS

It looks like jack might be compiled without OSS support. Are you running the new jack 1.9.2 version? According to this OSS is supported. Will look into it, but I have no real way to test it...

Ah, no, I'm running the one

Ah, no, I'm running the one bundled with the OS. Version 1.8.something-or-other. I'll give a go at compiling the newer one...thanks! Oh, I saw that message. That OSS backend is for Solaris systems. I was running under the assumption that JACK supports OSS, as there are menus in the control interface listing it...I guess a little more research is in order.
