    Im now using the trail version of Breakaway Asio.
    Sounds really great in my opinion.
    But I noticed something strange.
    When i have the ITE limiter switched on en BBP is showing the meters than the sounds starts to crackle.
    When i switch to Simple or Ossiloscope the crackling is gone??
    With the limiter off there is no problem.

    I didn’t calibrate the soundcard yet… 😳
    Don’t have the material to do that. 😳
    But can this cause the problem?

    My setup:
    D&R clubmate – BBP ASIO – transmitter (balanced in )
    BBP version: 0.90.78
    Soundcard: M audiophile 192 ( Does anyone know the tilt correction for this one?)
    Plugins installed:
    -dsp attenuator 6 db
    -impact clunck
    -bass efx
    Switching of the plugins doesnt have any effect.
    Also reinstalled breakaway.
    Cpu usage is 30 – 40 %

    Does anyone have solution for this problem?

    Lack of calibration does not cause crackling, so something else is wrong.

    What block size are you running?

    Hello Leif,

    Where can i find the " blocksize " value ?

    It’s usually configured in the ASIO control panel for your sound card.

    If you press Test in I/O options in breakaway, you’ll see the block (buffer?) size in the window.

    Also make sure you are using the latest vga drivers!

    When i press the test button:

    Backend active! ASIO buffer size 256

    Sample rate 192035,89

    Maybe there is a setting wrong in the control panel of the soundcard?
    I can make some screenshots if you like.
    I will also check if there are updates for the VGA drivers.

    I recommend trying buffer size 512. 256 places very strict timing requirements on the cpu – it’s possible that it’s not fast enough, but 512 should work fine.

    That seems to solve the problem… 🙂

    Thanks. 🙂

    By the way..
    I noticed there is a new release 0.90.87.
    I downloaded the 0.90.78 from the dowload section. 😕

    When is there going to be a new official release?
    Or can i use the beta versions for broadcasting safely?

    Or do you recommend to use the official release?

    As soon as I’m confident of long-term stability.

    The betas on the download page are known to be stable.
