I have compiled QtWebEngine into my i.MX6 embedded device. When I tried to play youtube Video with quicknanobrowser, the video plays but there would be no sound. In fact, there is no sound when I try to test play the audio files in hpr.dogphilosophy.net/test even though the website said that the browser codec is supported.
I have enabled pulseaudio, gstreamer, ffmpeg, opus, vpx, libwebp and yet still no sound.
However, I could play video with gst-launch and there would be sound.
Is it something wrong with quicknanobrowser that does not enable sound? Or is there components that I need to add to the embedded system?
Edit: Alsa and pulseaudio, GStreamer are all working fine with sound.
