Audio output low volume

    According to PicoCOMA5_Hardware_eng.pdf:

    The onboard soundcodec does support a stereo analog input and a stereo analog output for 1Vpp audio signals.


    Anyway audio output volume is very low, it can be decreased even more by amixer 'PCM' but cannot be increased.
    Output voltage on audio output is about +- 0,1V.
    Is there another setting for audio output volume?

    We are aware of the fact and have already found an error in the sound codec software. We will have a patch soon.

    The audio is fixed, but it is a little bit difficult to have a patch because it consists of several different changes that are interleaved in our version control system with other modifications. So we will have a regular new fsvybrid release soon, probably in two weeks, where the audio fix is one of the improvements. Is this OK for you?

    Unfortunately due to some very important commitments to high volume customers and new products that we have in our pipeline, we have to delay the Vybrid release again slightly. But from some of this other work, also the Vybrid implementation will profit, for example by a more up-to-date U-Boot version (at least 2014.07).


    To not further delay your work, we will send you a patch for the sound issue by e-mail.
