The quirk has been added to the 5.8 kernel and if I understand correctly will also be backported to LTS kernels.Įven with the quirk in place the left and right channels are swapped but this can easily be dealt with in software - either remapping while grabbing with ffmpeg or system wide with pulseaudio remap-sink for example. Without this the device is detected as a 0 mono capture device. To make stereo capture work with Linux you need a very recent kernel that contains an ALSA configuration quirk. As it's just plain HDMI this works to add DSP processing to Chromecast devices, Apple TV, FireTV sticks and the likes and also regular computers independent of operating systems. The video is MJPEG encoded and the audio is lossless stereo 16bit 48kHz PCM.įor anyone running a crossover/convolver/other DSP on a Raspberry Pi this provides an easy method to get sound into your DSP computer. These dongles expose a standard UVC webcam and a USB audio class soundcard to the system. Right now there are cheap USB HDMI capture devices being sold on AliExpress, ebay, amazon and the likes.
