Darren, >I have a few general questions for those people using DeMuDi, > >- Which version are you using - woody or sid? > Sarge. as i mentioned in a previous email, the "official release" of this will be in a few weeks. i was lucky enough to do a workshop with one of the developers a week ago, so i really got a lot of the bugs out! >- Is anyone using a sid DeMuDi over a sarge (or even woody) base Debian? > is there a Sid Demudi? anyway, for the record, here's what i did to get it running: i installed Woody with the ext3 file system, then updated to Sarge, built my own custom kernel with the low latency and preemptive patches [don't forget the devfs and reiserfs support!], compiled my Alsa and Jack, and got the Demudi apps. so, technically, i am only half-using Demudi. i skipped using the kernel, although i have gotten the newest kernel version running nicely on my laptop, there were still some issues with it keeping its Alsa settings and such. also, some hand-tweaking is required of the /etc/fstab to add the /dev/shm file system for the Jack. next step is to ditch the ext3 file system and replace it with reiserfs for smoother low latency operation, but that is beyond anything that Demudi would do right now... > >- How much software are you replacing with upstream source balls or CVS >versions? > i still get Alsa and Jack from source. especially Jack, as i want to seriously optimize it right now, so i am trying as many tweaks as i can find in the compile. i am not sure if the Demudi Jack version is optimized for realtime operation by users [instead of root, which crashes the shm file system anyway under Demudi], and if it is, then it may not be possible to use it with an ext3 file system on a 2.4.20 kernel without lockup. if Guenter or somebody else has patched the 2.4.20 Demudi kernel package against this, it is not a problem. but i don't know if all this is worked out yet. other than that, there are almost zero sound apps which i have gotten from upstream. many of the Demudi Sound Apps packages in the Sarge are compiled from CVS versions [espc. PD, Ardour, etc...], although probably not the LATEST in many cases, although the PD and related externals versions I can vouch for specifically as being only a week old! >- How 'usable' is your setup - I doubt that many have a workhorse >solution, although there seem to be a few success stories on this list >and elsewhere, but is it still really just experimental (in the Debian >sense of the word)? > with Jack fine-tuned, i see my setup being highly usable... plugging PD and Ardour together alongside my HDSP card is my main goal, and i think i am almost there. right now, it is just as experimental as i am..... best, Derek
