Every time I start my PC i have to open Sound Blaster control panel and double click the "Speakers - Headphones" slider in order to get sounds on. This feature appeared suddenly. Afaik I haven't change anything in the sound settings.
All the stuff are uninstalled/reinstalled and up to date. I use Logitech speakers. They are plugged in the rear panel "OUT". Headphones are Steelseries Siberia 800 and they are connected to SPDIF port. I have checked and rechecked everything but can't find anything dubious.
Any idea why this happens?
