 revision is involved, what behaviors do you get on another OS say windows
 where the audio is well supported ?


 It's desktop PC, a Dell GX280. Can the motherboard revision be read from
 the BIOS Serial number? Maybe it's printed on the motherboard? The same PC
 also runs Windows XP (my HDD has a Windows and a Haiku partition), and XP
 behaves as it should in this respect. Maybe you know a place inside
 Windows XP that shows the rev. number to the user?

 correct ?this could be a hardware design issue.

 Yes, I get sound, but the system speaker joins in on it.

 one could generate with such a chip. its likely the output may all be
 internally connected and there is additional control implementation on the
 chipset to configure which audio circuts are active.

 I didn't have this problem in an earlier Haiku revision (I'm pretty sure
 r38360 was okay). Also, the problem manifested itself before I removed the
 native auich driver and switched to OSS.[[BR]]

 To sum up: I once ran a Haiku revision using the auich driver with no
 problem (pretty sure that's r38360).[[BR]]
 Then, a later Haiku revision (that used the auich driver) had this
 problem.[[BR]]
 After that, removing the auich driver and installing the OSS one didn't
 remove the problem.

 So it seems to me it's not an OSS or motherboard incompatibility problem?
