Last modified: 2007-11-30 17:11:30 EST
Description of problem: No sound output on Sony VAIO Z600TEK.
Version-Release number of selected component (if applicable):
How reproducible: Always
Steps to Reproduce:
1. Boot laptop
2. Play sound
Actual results: No sound output at all. No errors or anything. Laptop appears
to be processing everything properly, but no sound output.
Expected results: Sound output
Additional info: This laptop was working perfectly happlily with Fedora Core 4.
Only thing that has changed is the new installation of FC5.
In older incarnations (Red Hat 7 & 8 - or thereabouts) there was an issue
whereby the sound wouldn't work if the network was connected first and the
network wouldn't work if the sound was playing. Something to do with a shared
chip for the sound and network. It was fixed in Red Hat 9 I seem to remember.
Could you please attach /root/scsound.log? (it's produced by s-c-soundcard)

Log file from system-config-soundcard
Hmm - please hold on this. The sound output is OK from the headphones. I'm
going to take the laptop apart to check for the internal speaker wires being
Will it work better if you choose the first sound device? the "Yamaha DS-1S
(YMF744)" device in system-config-soundcard. I think it could be a driver
problem, you can check the new ones (http://people.redhat.com/stransky/alsa)
sorry, the first one is "YMFPCI [YMFPCI]"
