Have done the following: 1) Swapped boards - no change 2) Applied the patch - no change (we were detecting the WM8775 OK anyway and the other changes were either non HVR-1300 or we had already tried them so probably not too surprising 3) Made sure I2SINPUT is enabled - no change So still have the following strange observations: 1) Repeatedly swapping between inputs eventually gives us audio 2) Once fixed it survives a warm reboot but not power cycle 3) Putting a scope on the I2S line out of the CX2388x shows noise when TV input selected and no noise for Composite (unless inject a tone). However MPEG-2 audio always contains hiss or hiss plus injected tone. So looks like two issues to me. I'll try and modify the driver so that when switching inputs we only config the WM8775 or the CX2388x or the MPEG encoder and see if I can determine which item has the configuration issue.
