Soundblaster Live: Didn't work -> Now works



My Soundblaster Live! was functional when I ran redhat 9 on the same computer I'm now running Fedora Core. With FC3, whenever I playback anything, the playback-application hangs. When mplayer starts a movie, I see the first second and a half, and then the picture just hangs. mplayer is still running and I can gracioiusly exit mplayer with 'q'.

The SB Live is apparently recognized. It's not sharing an interrupt and fwiw, the card is 'passively' functional. I have a Hauphauge TV card of which the audio output is connected to the SB's Linein, and when I watch TV I can clearly hear the TV sound which the SB patches through (via Speaker out) to my speakers. I can't adjust the volume, however.

I just upgraded my system to FC4, but the problem persists. lspci reports the SB Live as a 'VGA compatible unclassified device' and this lead to a suggestion that seems to have solved the problem. I issued the following commands:

cd /usr/X11R6/lib/modules
sed 's/scanpci/pcidata/g' < libscanpci.a > libpcidata.a

after having backed-up libpcidata.a. After a reboot the SB Live suddenly works now. lspci still reports the SB Live as a 'VGA compatible unclassified device'. I had to run aumix to increase the volume of PCM2 (which previously didn't help), and now I can adjust mixer settings from gnome-volume-control.

I'm using ALSA and have no problems anymore. Moreover, my computer seems to be running much faster with FC4 (and FC3) than with redhat 9. My disks are screamingly fast. In redhat 9 I would get about 23-27 MB/s disk reads and 95-100 MB/s cache reads. With FC4, my disk reads are a whooping 36-39MB/s and cache reads are an incredible 242 MB/s. When I used to burn a DVD (cdrecord-prodvd) with RH 9, my system would become effectively unusable while burning. Now when I burn a DVD in FC4, I don't even notice that the burn process is taking place (other than blinking LEDs on my DVD burner and HDD activity indicator).

What more can a 21st century person ask for?
