I am trying to use MythTV with a Hauppauge WinTV-PVR-PCI card on Redhat Linux 8.0 machine. After searching the web, I found out I have to copy the firmware file to /usr/lib/video4linux/hcwamc.rbf, which I did. I have not made any changes to the kernel. I then run xawtv to see if it is working. I get video, but no sound. I tried plugging headphone directly to the tuner's line-out and I hear absolutely nothing. Loaded modules are: Module Size Used by Not tainted tuner 11424 1 (autoclean) tvaudio 14332 0 (autoclean) (unused) bttv 78496 0 (autoclean) i2c-algo-bit 7912 1 (autoclean) [bttv] i2c-core 17796 0 (autoclean) [tuner tvaudio bttv i2c-algo-bit] videodev 7584 3 (autoclean) [bttv] sr_mod 16344 0 (autoclean) cdrom 30304 0 (autoclean) [sr_mod] i810_audio 26088 0 (autoclean) ac97_codec 13064 0 (autoclean) [i810_audio] soundcore 5956 2 (autoclean) [bttv i810_audio] autofs 11924 0 (autoclean) (unused) smbfs 38000 1 (autoclean) 8139too 16488 1 mii 3592 0 [8139too] sis900 14796 1 ipt_MASQUERADE 2008 1 (autoclean) iptable_nat 19544 1 (autoclean) [ipt_MASQUERADE] ipt_REJECT 3608 2 (autoclean) ipt_LOG 3992 7 (autoclean) ipt_state 1016 4 (autoclean) ip_conntrack 25192 2 (autoclean) [ipt_MASQUERADE iptable_nat ipt_state] iptable_filter 2284 1 (autoclean) ip_tables 13624 8 [ipt_MASQUERADE iptable_nat ipt_REJECT ipt_LOG ipt_state iptable_filter] ohci1394 18184 0 (unused) ieee1394 44108 0 [ohci1394] mousedev 5108 0 keybdev 2688 0 (unused) hid 20228 0 (unused) input 5504 0 [mousedev keybdev hid] ehci-hcd 17576 0 (unused) usb-ohci 19784 0 (unused) usbcore 71360 1 [hid ehci-hcd usb-ohci] ext3 61856 5 jbd 46676 5 [ext3] ide-scsi 10672 0 sd_mod 12844 0 (unused) scsi_mod 100664 3 [sr_mod ide-scsi sd_mod] Any help would be appreciated!
