I believe the speakers are analogue, but I don't know for sure - there's |
| 40 |
nothing in any documentation to say so, and I couldn't find anything |
| 41 |
relevant on the net. They're a pair of Altec Lansing "expressionist |
| 42 |
BASS", black desk standing speakers that look a bit like daleks |
| 43 |
(mechanical badies from the british science fiction series Doctor Who). |
| 44 |
|
| 45 |
I've set both S/PDIF and "S/PDIF Default PCM" to muted. No joy. |
