[linux-audio-user] lost user access to alsa

[plutek]

greetings!

i'm using a laptop with ubuntu dapper, 2.6.15 kernel (with ingo's patch), alsa 1.0.10, and jackd 0.100.0.

this system was working flawlessly with with both the onboard soundcard and my RME Multiface, with realtime access as user, until a recent install of some dvd-playing apps. now, when i try to bring up jack *as user* i get:

---------------------------

-------------------------------

the same command line *as root* works fine.
i don't know what has changed.... can someone help me sort this out?

many thanks in advance!
