    BUT, I have just tried with the 1.95 and strangely the sound is completely distorted.
    I have switched several times between 1.94 and 1.95, restarted Windows : it is always the same, the sound is perfect with 1.94 and distorted with 1.95 (same project and same settings of course).
    With a sine test signal, the sound is clean when there is no amplitude change but there is a noise (like a zipping noise) as soon as it changes.
    So with a normal sound there is always the noise.
    I suppose that it is related to the ASIO4All driver and the sound cards on this computer, but there must be some difference between 1.95 and all previous version since I haven’t had this yet.
    Any idea ?

    If you bounce the master, is the zipping noise present in the bounced recording?

    No, it is only a problem with the driver. I hear it in Podium but if I open the file in another one the sound is good.

    The zipping noise occurs both when using expanded and compact modes?

    Yes.

    Is the Podium CPU indicator behaving differently between 1.94 and 1.95 beta?

    Yes, it is very low.
    With the simple sine test it is about 2 %.

    I have tried with the beta 6 and the result is the same 😥

    Are you sure that nothing else than the GUI has changed from 1.94 to 1.95 ?
    It is annoying since the compact layout will help me a lot in my project…

    There are no changes to the engine since 1.94. The track routing code has been modified to check for the compact mode, but I can’t see how that should affect audio playback.

    Do you run antivirus, spyware or firewall software on your laptop? Maybe these will probe the activities of the Podium beta since it is run as an .exe that is not a proper installed application. Just a wild guess.

    Do you experience the distortion even with a simple arrangement playing a single sound file without any plugins?

    Is the distortion affected if you increase the ASIO buffer size?

    No, no Internet connexion, no antivirus etc.

    Do you experience the distortion even with a simple arrangement playing a single sound file without any plugins?

    Yes in all cases, even with only one track and one plugin that generates a sine wave.

    There is no change whatever I make in Podium’s buffer size or ASIO4All settings.

    The sound is always good when I run 1.94 or other programs like Bidule, Reaper or others, with the same driver settings (18 output channels with 3 USB soundcards).

    Have you tried the 1.95 beta on another PC, and if so did the distortion happen there?

    Try switching to Wave drivers instead of ASIO4ALL on your laptop, and check if the distortion still happens.

    The distortion appears only with ASIO4All with this configurations on this PC.
    There is no problem with another one with different soundcards.
    If I supress a sound card from ASIO4All it is also OK, but need it !

    The problem for me is that I cannot use another soundcard configuration onh this computer, so I can of course continue with 1.94, but when you will add time-stretching it will be hard to satisfy with it 🙁

    The only question is : why does it work well with all versions prior 1.95…
    Mystery !

    Mystery !

    Indeed. I assume you are using the latest ASIO4ALL 2.8 beta 2. I see on the website that there are options for disabling the new watchdog feature. Perhaps you could try this, or maybe try an older version of ASIO4ALL.
