No sound. Please help.

[Q]

Hi everyone, this is another problem with RH 9.0 Severn Beta 1. For some reason I can't get any sound output. I am using digital SPDIF out put to an external Dolby digital decoder. Here is my specification list: - Northbridge : VIA KT400A - Southbridge : VIA 8235 - VIA VT6306 IEEE1394 controller - Super I/O : ITE IT8705F - Silicon Image sil3112A controller - Raeltek 8100BL Ethernet 10/100Mb LAN controller - AC97 Realtek ALC650 6-channel sound Chip - Realtek ALC650 AC97 codec Chip - Dual BIOS On RedHat 9.0 my onboard sound worked flawlessly and required no additional configuration from me. Any input you can offer is welcome. Q
