Hi, I think I read all the mails about sound problems in FC2. My problem is that my sound is sometimes here, and not in the next boot, but should come back maybe next time ... So this is not easy to understand. I tried everything, alsamixer, play test sound, aumix, and these are the result. - My sound card is recognized ens1371. - Testing sound card does not work. - Alsamixer / aumix / volume control has all volumes set high and not muted. - My /etc/modprobe.comf is below : alias eth0 8139too alias snd-card-0 snd-ens1371 install snd-ens1371 /sbin/modprobe pcspkr && /sbin/modprobe --ignore-install snd-ens1371 && /usr/sbin/alsactl restore >/dev/null 2>&1 || : remove snd-ens1371 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-ens1371 alias usb-controller ehci-hcd alias usb-controller1 uhci-hcd [root@P4 etc]# lsmod | grep snd snd_pcm_oss 41000 0 snd_mixer_oss 13824 3 snd_pcm_oss snd_ens1371 17380 3 snd_rawmidi 17444 1 snd_ens1371 snd_seq_device 6152 1 snd_rawmidi snd_pcm 69256 2 snd_pcm_oss,snd_ens1371 snd_page_alloc 8072 1 snd_pcm snd_timer 17284 1 snd_pcm snd_ac97_codec 54788 1 snd_ens1371 gameport 3328 1 snd_ens1371 snd 39396 10 snd_pcm_oss,snd_mixer_oss,snd_ens1371,snd_rawmidi,snd_seq_device,snd_pcm,snd_timer,snd_ac97_codec soundcore 6112 3 snd /var/log/message shown the classic FATAL error sound-slot-1... P4 modprobe: FATAL: Error running install command for sound_slot_1 What I know, is that maybe the next boot (!), I will have sound, maybe not. Where does this instability come from ? Do I have to think that a reboot should fix the problem, as I used to think on another OS before ;-). Or do I have a hardware problem ? But anytime I boot in RH9, I always have sound ... Thnaks, for your help. Philippe -- Philippe, Chiangmai, Thailand
