tried nobody/nogroup, audio/audio still did not work. seems to center
around missing /dev/dsp also all the oss libs are installed but still
dsp not created and usual methods of modprobe either gen errors or don't
create /dev/dsp
Maybe someone in the forum can opine whether I have got the big picture
of audio right below:
1. on startup the kernel detects all hardware and loads all needed
modules for existing hardware.
2. when ALSA is chosen to be used, these modules are configured such
that they communicate with the ALSA server first then the hardware.
3. when JACK is installed it wraps ALSA with an additional layer such
that all inputs and outputs from ALSA are first fed through JACK thence
back to ALSA and then the hardware via the modules once the connections
are defined in JACK connections.
4. JACK aware applications talk to JACK which communicates with ALSA
thence to the hardware modules.
5. NON-JACK aware applications communicate directly with ALSA and thence
to the hardware supposedly; NO? but they don't when JACK is running
(unless alsaloop is running as some suggest)
6. All applications, jack-aware and non aware, will work via ALSA
directly when JACK is not running.
PulseAudio has been removed and omitted from the big picture becuz it
just makes people more confused and their heads hurt. ***grin***
Thanks

Is installed the same as all the other media programs like
audacity, alsaplayer etc and run the same; they work darkice
doesn't. I will give it some thought this weekend though. all were
installed under sudo, you may have a point qjackctl is run by a
user, as are all the media players and editors; but darkice has to
be launched as sudo which is different that qjackctl

Hello all,
I have installed ALSA,JACK, and Darkice. Jackd2 is running in
real time no problem and audacity, ardour, alsaplayer and
aqualung all wok as advertised with it.
Where I have a problem is Darkice, I cannot get it to connect
to icecast2 server input nor show up in Jack
Connections/Patchbay. Icecast2 is workting fine and when I
click on the "listen Live" link on the station website it
opens alsaplayer as it is supposed to; so I assume all is
well with icecast2.
Thanks, Andy
the problem is as below (and if someone could point me to a
patch and procedure to apply it) :
