When resuming from suspend, where sound output was set to PCM2902 Audio Codec Analog Stereo (USB UCA202 device output to stereo system.) Then sound will not resume. It is not muted.
I have to manually reselect PCM2902 in sound properties since it will have switched back to Internal Audio Analog (though no sound out of monitor speakers.) Whereupon reselecting the USB card, sound will resume but will need to be un-muted first.
There is no problem suspending when sound properties is set to Internal Audio Analog Stereo (monitor speakers.) PC will suspend & resume playing sound no problem.
Should I report a bug to Launchpad or is there a workaround?
