    picoreplayer USBridge auto on AMP

    Hello, I'm using latest pcp6 and Allo USBridge. USBridge->USB->AMP (Primare)
    I'm very happy with this combo but there is one thing not working.

    If I start playing music and my AMP is off it is supposed to get switched on automatically by USB signal.
    It's working with a different software (I think it was DietPi) but not with pcp6. I've tried also previous version of pcp with no success.
    Do you have any idea how to fix?

    cheers Sebastian

    My guess is that there is a piece of software controlling the amp......do you have any info on your DAC....perhaps a link.

    There is not so much information about the integrated dac of the amp:
    https://www.primare.net/products/i15-prisma-2/

    I could probably manage switch on by rpi's gpio to rs232 input of the amp.
    But would be nice if it's working just over USB like with other OS. For me there is no alternative to pcp.

    I've ask also producer of the Amp maybe they can give a hint what to check.

    How about the auto-sense setting ... try setting it to WAKE+SELECT ... with STANDBY set to NORMAL

    "AUTO SENSE
    Choose between: SELECT to automatically select an input
    containing an audio signal if the I15 is on; WAKE+SELECT
    to automatically wake up the I15 from standby, if
    necessary, and select an input containing an audio signal;
    and OFF (default) to disable automatic switching."

    "STANDBY MODE can be set to ECO to reduce the standby
    consumption to less than 0.5W, but only allows the I15 to
    wake from the analogue and digital inputs, or NORMAL
    which also allows the I15 to wake from streaming and the
    PC/MAC input."

    Thx for the hint but both is OK. With all the same but different OS it's working fine.

    What happens if you plug the Primare directly into the RPi and then configure pCP to drive it directly?

    There must be a driver or user space program needed.

    OK, I got information that auto sense is working when usb device is powered off and switched on again. I can agree. Since my streamer is running 24/7 it's not working because there is a constant link without level.
