I have a Onkyo TX-SR705 receiver. When I hit the Muting button the volume gets extremely loud. I tried to set the Muting Level in the Volume Settings menu but it will not respond. It is stuck at “-56db” and cannot be changed. Any ideas?
If what Dark_Orbit said does not work try doing a master reset by ressing and holding the dvr/vcr button and stand by button simultaneously. This would erase all your assignments so you would need to reassign all your sources hooked up to your onkyo.
I had the same problem. I finally sent the unit back to Onkyo for repair. They said that the control board was replaced and the firmware was updated. This was about a year ago and the problem has not returned.
Check your setup:
*press setup
*go to Miscellaneous
*go to volume setup
*go to muting level
*make sure that the muting level is on minimum (press the left arrow or the left preset button)
*if it shows a negative infinite sign (its measured in decibels) its ok.
you can now mute it without the loud noise.
