Hello. \n\nGot my dad's old Yamaha RX-A2010 this year. Everything was working fine for couple months. No problems whatsoever. \nI' am using a 5.1 setup (was planning an upgrade to 9.2 setup, guess not) Yesterday noticed that my speakers are all muted. Except subwoofer. Still working just fine. \nI ran the test tones option in settings and still no audio from front,center and surround speakers. Subwoofer works fine. \nI'm guite new to home theater systems and i tried already to find solution to the nasty problem i'm having. \nGuessing it's a hardware malfunction. Maybe something got broken. Don't know. \nDoes anyone have any advice? \n\nP.s speakers work normally with my older Sony receiver.\n\nGreetings from finland. Summers coming.
