Still have some light "snap, crackle and pop" problems here. They don't seem to be related to X-runs. I set Qjackctl in "Soft mode" but don't know if that matters? I have run this thing 8 ways 'till Sunday! Forget 96kHz! It does it intermittently with Chorus on a single mixer channel in Ardour patched in Qjackctl from the Mic preamp in 1 of the 1010 to the Ardour channel with Chorus LADSPA plugin and then out to output 5 of the card and into my mixer. I also run reverb in another channel with dedicated I/O's from the sound card as I do with a delay. I have raised the buffer rates and tried different (lower) sample rates. etc. I have /tmp setup as tmpfs although Gnome system monitor does not always show that it is there? I'm using the "default" setting in Qjackctl. I have not been able to get a .asoundrc setup for HW:0 that gives me the 8 ins and outs. Would this be part of the problem? This is on an Asus A7V8X-MX SE Mobo with 2500 Athalon XP. 512M Ram...Delta is the ONLY card in the PCI slots. Onboard audio disabled. ALL unnecessary peripheral stuff turned off in BIOS. Delta on IRQ 10 with nothing but system devices on prior interrupts. All in Mandrake 10.0 running the tried and tested 2.4.22mm kernel. All being run as root. It is close in terms of quality but for this intermittent popping. I have 2 gigs Saturday and am running out of ideas. Desperately yours, ;/ Russell
