Maybe this has been solved already. I remember participating in a 
discussion over default sr being hardcoded to 44100. Is there currently 
an option to specify "use the system sr" when using -odac and a backend 
with a fixed sr (jack) ?

I'm not sure about this, but you can override the orchestra SR using
the ```--sample-rate=N``` command line flag. I do this when loading
Csound instruments in a DAW, so that they use the same SR as the host.

I know about that. I was secretly hoping that csound would be smart 
enough and when leaving sr unset it would use the system sr, but it 
defaults to 44100. In most cases the backend has a fixed samplerate and 
csound already knows about it, so the question is: would it be possible 
to default to the system sr when no sr is present and output is to dac? 
Or maybe add a possibility to do something like `--sample-rate=system`?

The only thing that exists at the moment is --get-system-sr to query the system sr:

csound -odac --get-system-sr

I’ve added the option --use-system-sr which should do the job. It needs -odac or similar
to be defined first, e.g.

csound -odac0 --use-system-sr test.csd

Thanks for this. I tested it but I can't get it to work as expected. I am working in linux and if jack is configured with sr=48000 the following csd will not work. I tried changing the order of the arguments, or passing these at the command line, but I always get the error

system sr: 48000.000000

No, it doesn’t work with Jack. I think it is to do with the double loading that we need to do to
get the sr from the system. Might need to do something different.

I would have thought that with suitable flags one could redo the sr calculation late.

So I had a closer look and by re-ordering the operations I managed to provide a better
implementation of the --use-system-sr flag. Tested with portaudio and jack.

Only relevant with realtime output, no-op if other output destinations are used or
if the sampling rate is overridden with another option. 
It is also only guaranteed to be implemented with Csound output modules. 

The flag might not work with host implemented IOs, which need to call the following
function as early as possible, certainly before csoundStart() to record the
value of the system sr.

  /**
   * If val > 0, sets the internal variable holding the system HW sr.
   * Returns the stored value containing the system HW sr.
   */
  PUBLIC MYFLT csoundSystemSr(CSOUND *csound, MYFLT val);

I can't get this to work. In particular, using a file without any options inside CsOptions and calling it with

csound -+rtaudio=jack -odac --use-system-sr srtest.csd

keeps trying to use 44100 as a samplerate, independent of jack being configured to use 48000.

<CsoundSynthesizer>

</CsOptions>

<CsInstruments>
ksmps  = 64
nchnls = 2
0dbfs  = 1

I'm not sure about this, but you can override the orchestra SR using
the ```--sample-rate=N``` command line flag. I do this when loading

Maybe this has been solved already. I remember participating in a
discussion over default sr being hardcoded to 44100. Is there currently
an option to specify "use the system sr" when using -odac and a backend

yes, I had to adjust the jack module for this. Try now.
ALSA is not for this ready yet, I have to go into linux to fix it.
