I took a disk out of one computer, and put it in another (more precisely, I took out the Utrabay hard disk from a ThinkPad T20 and put it in a ThinkPad T23) and now I am told there is no sound because "Device /dev/dsp does not exist". How exactly does one ensure that this device is created? There seems to be a rule in /etc/udev/rules.d/ KERNEL=="dsp*", MODE="0660" I take it this just says that if /dev/dsp is created it should have mode 0660? I googled quite extensively for "fedora udev dsp" and came across a large number of queries and a few answers which I tried without success. Several referred to "alsaconf" which does not seem to be available in FC-5. I seem to have modules running which should create /dev/dsp , as shown by the partial lsmod list below. I'd be very grateful for a solution to this conundrum: how do I create /dev/dsp, and why has it not been created for me? --------------------------------------- snd_emu10k1_synth 6464 0 snd_emux_synth 32032 1 snd_emu10k1_synth snd_seq_virmidi 5120 1 snd_emux_synth snd_seq_midi_emul 5888 1 snd_emux_synth snd_emu10k1 114180 1 snd_emu10k1_synth snd_rawmidi 18912 2 snd_seq_virmidi,snd_emu10k1 snd_ac97_codec 92032 1 snd_emu10k1 snd_ac97_bus 1792 1 snd_ac97_codec snd_seq_oss 29888 0 snd_seq_midi_event 5888 2 snd_seq_virmidi,snd_seq_oss snd_seq 45744 7 snd_emux_synth,snd_seq_virmidi,snd_seq_midi_emul,snd_seq_oss,snd_seq_midi_event snd_pcm_oss 34624 0 snd_mixer_oss 15424 1 snd_pcm_oss snd_pcm 65640 3 snd_emu10k1,snd_ac97_codec,snd_pcm_oss snd_seq_device 6348 6 snd_emu10k1_synth,snd_emux_synth,snd_emu10k1,snd_rawmidi,snd_seq_oss,snd_seq snd_timer 18180 3 snd_emu10k1,snd_seq,snd_pcm snd_page_alloc 7656 2 snd_emu10k1,snd_pcm snd_util_mem 3328 2 snd_emux_synth,snd_emu10k1 snd_hwdep 6660 2 snd_emux_synth,snd_emu10k1 snd 42916 13 snd_emux_synth,snd_seq_virmidi,snd_emu10k1,snd_rawmidi,snd_ac97_codec,snd_seq_oss,snd_seq,snd_pcm_oss,snd_mixer_oss,snd_pc --------------------------------------- Incidentally, is there any way of re-starting the sound system apart from re-booting? Why can one not say "system sound restart"? -- 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
