- Add FixChannelLayout() helper to AudioProcessor::Open() to fall back to a default native channel layout when the input/output layout is unspecified, custom, or has a zero mask. This prevents FFmpeg's abuffer/aformat filters from rejecting 'channel_layouts=0x0' on Linux. - Log audio processor open parameters, viewer audio queue state, and AudioManager::PushToOutput device/stream status to help diagnose silent playback on Linux.
