Hello,
I have to be able to have audio after terminating jackd. Everything
works fine when jackd is present, xine, firefox, audio apps, etc. When
jackd is gone, no more audio. Taking xine as an example, pavucontrol
will show the output when it plays a video and will show that the
output goes to the onboard audio. If I choose the 1010LT card, then
xine freezes. Envy24 utility shows nothing.
I would like to be able to view, and hear, downloaded video clips
without jackd around.
Why ? Because the current bitwig has a bug in which jackd MIDI does
not work. This translates has having sound, but no MIDI from external
controllers. OTOH, if bitwig switches to ALSA then there's MIDI but no
sound until jackd goes away.
The goal is to follow bitwig tutorials.
There must be a way for audio apps to be able to output sound on the
1010LT without jack...
1) if an application is written to ONLY use JACK, then JACK must be running for that application to output audio
2) if an application is written to use JACK or some other audio API, then obviously JACK can be be stopped and the application can be told to use another API
3) if an application is written to use some other audio API, then in general, it will be a little complex to get it to work if JACK is running, and trivial if it is not.
However, if your system was setup to deal with case (3), so that non-JACK applications could be heard even when using JACK, then it is unlikely that those same applications can be heard if JACK is not running.
For example, on my own system, JACK is the sole user of the only audio interface I have that is connected to any speakers. All non-JACK applications end up talking to PulseAudio (either directly, like Skype or a web browser (for shame!)) or indirectly (via PulseAudio acting as the default ALSA device). PulseAudio and JACK are connected via an ALSA loopback device. If JACK is stopped, the non-JACK applications will continue to function, but they cannot be heard.
So ... the way forward depends a great deal on the specifics of your system and the applications in question.
