ok guys, I have an IBM ThinkPad 600X. Sound in Red Hat Linux 9.0 worked fine, but not in Fedora Core 4. The sound chip is a Crystal Semiconductor CS4614. Running "Soundcard Detection" from the default GNOME menu detects the chip just fine, but clicking Play Test Sound yields only silence. Typing aplay at the command line returns the following: [begin quote] ALSA lib conf.c:1578:(snd_config_load1) _toplevel_:51:23:No such file or directory ALSA lib conf.c:2821:(snd_config_hook_load) /etc/alsa/cards/aliases.conf may be old or corrupted: consider to remove or fix it ALSA lib conf.c:2684:(snd_config_hooks_call) function snd_config_hook_load returned error: No such file or directory ALSA lib pcm.c:1959:(snd_pcm_open_conf) Invalid type for PCM default definition (id: default, value: cards.pcm.default) aplay: main:508: audio open error: Invalid argument [end quote] Any ideas??? :-/ btw it works fine in Windows as well... I tried modifying modprobe.conf as directed at the alsa-project.org site, to no avail. Same result. Also tried chmod a+rw on /dev/dsp, /dev/sequencer, and /dev/mixer. There is no alsaconf on Fedora Core 4 apparently, at least not by default, so I found an RPM for it and ran that, its modifications of modprobe.conf didn't change anything, so I removed them. One more thing: after running aplay, and exiting Xorg, standard output has the comment "ALSA device "default" had an error". So that might have something to do with it as well. Please help! --Brian, 27 male, "Silicon Valley" __________________________________ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs
