So, I disconnected and reconnected and even tried a different cable. So, it seems the machine isn't detecting the fact that the speakers are connected via TosLink. I am connected via optical TosLink cable.įWIW, in the Realtek HD Audio Manager > Speaker Configuration tab > only 2 speakers are showing, and in the Speaker configuration sub-section, Stereo is selected and grayed out/greyed out/disabled.

Every time, I see the 'DECODE' light actuated on my Logitech Z906 'receiver.' I check the General tab > Jack Information > Rear Panel RCA Jack - which is incorrect. I click the Advanced tab > Default Format is Dolby Digital Live (5.1 Surround) > Test > I hear the same test sound from the Front-Left, a pause (which would presumably be the center channel), then the proper test sound from the Front-Right.and that's it. I test it in Windows Sounds > Playback tab > double-click Realtek Digital Output > Supported Formats tab > under Encoded formats, select Dolby Digital > Test > I hear 6 discrete sounds from 6 discrete separate channels properly (5 + sub). I run Overwatch around March 8, and suddenly I only hear sound from the Front-Left and Front-Right speakers. As my character rotated, the sound would move from speaker to speaker properly, as expected. If a gun was firing behind me and to the right, I heard it from the right-rear speaker.

I could hear discrete sounds from all 5 individual channels, depending on my position. The last time it was working properly was probably around early February. I only hear sounds from the Front-Left and Front-Right speakers. I disabled Secure Boot, Driver Signing, and Defender, then followed these instructions, and I was able to get DDL and DTS Interactive showing in Realtek HD Audio Manager, but it's not working properly in games like Overwatch. I'm running a 2010 Mac Pro with OpenCore and UEFI dual-booting macOS and Windows 11 21H2 (22000.652) - so the latest version.
