    Hi,

    Is it possible with Qt to connect to multichannel sound card like gigaporthd and play different sound to each channel? Like playing multiple language text to each channel.

    Best Regards
    Marek

      Hi,

      It depends a bit on how the card presents itself to the system. However advanced mixing is currently not part of QtMultimedia.

        Hi

        I thought about different solution. To make wav file encoded with different text played into separate channels and then setChannelCount to proper value.

            Like in this example QAudioOutput Class
            format.setChannelCount(1);

            setChannelCount(8) - should send 8 channel encoded stream. I suppose.

              That's right,

              I misunderstood your idea using the channel count
