Thanks for your response. I now have /dev/dsp, but still no sound! I discovered, as was suggested, that I did not have an appropriate driver for the sound card (Intel 82801CA/CAM AC'97 according to lspci) in my ThinkPad T23. I had assumed (from a quick look on the web) that I needed the ALSA OSS-compatibility module snd_emu10k1 but it seems that this is not sufficient on its own. I now have the module snd_intel8x0 running as well, and this is shown (eg on running system-config-soundcard) as the module attached to the soundcard. This says that the "Default PCM Device" (whatever that means) is "Intel ICH [Intel 82801CA-ICH3]". What I don't understand is the various aliases that it has been suggested one should put in /etc/modprobe.conf . I now have ------------------------------------------ alias char-major-116 snd alias char-major-14 soundcore alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss #alias sound-slot-0 snd_emu10k1 #alias snd-card-0 snd_emu10k1 alias snd-card-0 snd-intel8x0 ------------------------------------------ But I have no idea what these instructions mean and have been unable to find information on them on the web. (The official [tldp] Linux Sound-HOWTO is dated 2001, and seems more or less useless.) -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
