PC Chips M757 sound problem

More problems than a long tailed cat in a rocking chair factory.

PC Chips M757lt with SIS 7018 sound onboard. New fresh install of Win98SE and everything works well except their is NO sound out of the CDROM drive or MS Media player. The MS Media player 7.1 tells me that there is no sound card installed BUT, when I turn on the PC the sound plays normally. Also in device mngr, sound it plays O.K. I reinstalled the drivers from the setup cd, checked every possible box in entertainment and sound options including the digital sound etc. with no change. First time I have encountered a sound device that will play the windows wav. files on start-up but no CD or wav files. HEEEEELLLP.

Well, I didn't get any response to my dilema so I had to solve it myself....
Reformatted the HD, reinstalled Win98SE. Instead of using the automatic installation of device drivers in the setup cd provided by PC Chips, I disabled the devices in bios then loaded them individually, one at a time, sound drivers first and all is well. CDROM sounds works as well as MS Mediaplayer.Lots of work but any port in a storm.

So you just had the wrong drivers on the sound device.

And there's really no reason to complain about no answers given when you're THAT impatient. I mean, not even four hours between thread start and epilogue ...

Lighten up...I was responding in jest. I know humor is absent in some areas...:r :r :r

I was simply happy because I discovered the problem. Peter, I DID NOT HAVE THE WRONG DRIVERS INSTALLED. They were SIS 7018 drivers that the automatic setup cdrom installed. The automatic install placed 3 devices on interrupt 11 and they were interferring with each other. I know your take on irq sharing, but it ain't necessarily so. GET IT?

So you had the right drivers but stacked on top of each other the wrong way round.

Just out of interest, what audio codec is attached to the SiS 7018 engine? A C-Media by any chance? If so, you should be using the C-Media driver rather than the one from SiS.

Quit honestly, I simply let Windows and the PC CHips setup disk load the drivers automatically. It selected the 7018 engine.
I saw no reference to C-media in the setup. This was a format and clean install of Windows98SE, No other devices loaded until I ran the setup disk.
It's quit acedemic now, as it's working perfectly after I disabled all the devices in the bios then loaded them one at a time individually.

I'm asking because if you don't have the right driver for your sound engine/codec combination, the mixer application won't have the channel and volume assignments right - leading to surprise silence. Check it for your own sanity ;)
