Title: audio group in tinycore (real time jack option)
Post by: P5music on November 01, 2010, 05:59:02 AM
Hello,
I am using (also) Linux Mint Kde 9 and I am able to use windows audio applications (Reaper+SampleTank2) without glitches with wine/wineasio and jack with real-time option.
But it was necessary to add my user to audio group and edit limits.conf.
Now I ask if it is possible to do the same in Tinycore to get rid of the glitches there too.
Thanks

The startup script should be doing that automatically, and it does for me.  Here are the relevant lines:

Code: [Select]
sudo addgroup audio > /dev/null 2>&1

sudo addgroup "$USER" audio > /dev/null 2>&1

P5music: Have you actually verified your current situation (e.g. via grep audio /etc/group)?

the result is
audio:x:1000:tc

P5music: I trust you realise that 'audio:x:1000:tc' means that the two commands quoted by Jason in reply #1 have been executed correctly (i.e. the additional group 'audio' has been created, and the user 'tc' has been added to that group).

So what else do you believe is missing?

What part of thestartup script are you refering to?


See set_rlimits.tcz to permit realtime-mode. A set_rlimits.conf.example is included.
I hope this doesn't come too late. There didn't seem to be anybody else besides me interested in using tinycore as a daw.

There are no problems whatsoever. I have very low latencies here (http://forum.tinycorelinux.net/index.php?topic=873.msg35775#msg35775).

are you using 3.x ?
if yes, could you list the extensions you are using (related to daw)?

Nope, this works for me on 2.x: set_rlimits, jackd-ffado, qsynth
You could try something like that on 3.x obviously.
