Hitachi projector Standby audio setting greyed out

[richardg7vyi]

We have some new Hitachi short throw interactive projectors. The audio is fed through the projectors and I want to set audio from PC to be passed through in standby. This is normally done by going to audio settings and stepping down to the standby option to select an audio source and that's it job done. This has worked on the other projectors. However on one projector this option is in menu but greyed out with setting defaulted to muted audio in standby .

I've reset all settings to default and tried again but still the same greyed out option. Has anyone any idea why this might be, as I've failed to get a reply from Hitachi at present?

Hi Anthony

Current connection is PC (computer1 and stereo jack audio) > projector > speakers on wall. On other projectors of same model we have selected the appropriate audio source for the standby audio setting and sound is still relayed out to external speakers when projector in standby. On this particular projector though the standby sound option is greyed out in the menu so you cannot select it to set the option for some reason.

Can I ask why you don't go straight to the speakers instead of through the projector first?

[richardg7vyi]

That has always been my preference to wire speakers directly not via projector on previous installations. However we are now in some cases using wireless HDMI video devices to allow teachers' MS Surfaces to connect to projectors. This routes sound via HDMI into the projector so it was decided that sound should be routed through the projector to external speakers for all. I have bypassed the projector in some cases where issues have occurred as It does seem to attenuate the audio slightly in standby too which was bringing complaints from the music department.

Is this only not working on 1 projector, what model is it?

A quick Google suggests that these settings are disabled if the projector is set to "saving" standby mode in the setup menu?

[richardg7vyi]

I did try playing with those settings before and it didn't seem to change anything. I wonder though if it needs power cycling after changing it? Couldn't seem to find anything on google the other day. I've now discovered another projector of a different model doing the same. So must be a setup issue somewhere.

I have now resolved this problem. It is as suggested by bald_pig the setting of Standby mode. I had only looked at the Eco settings before. Standby Mode is only listed under Advanced Menu>Setup then the Standby Mode option. Set this to Normal and the audio setting for standby become accessible. All working now. Funnily enough later this morning I had an email back from Hitachi from my enquiry a few days ago suggesting the same and showing location of menu setting. Edited November 2, 2015 by richardg7vyi
