update: I booted into an ubuntu live cd and the um-1s worked, I took a look at the loaded modules (a LOT!): (the arrows shows which modules I did not have) snd_rtctimer snd_usb_audio snd_usb_lin --->snd_hwdep ^these were loaded after inserting the device I think snd_hda_intel snd_hda_codec --->snd_pcm_oss --->snd_mixer_oss --->snd_pcm snd_seq_dummy snd_seq_oss --->snd_seq_midi --->snd_rawmidi snd_seq_midi_event snd_seq --->snd_timer snd_seq_device --->snd --->soundcore --->sndp_age_alloc (used by snd_hda_intel, snd_pcm) --->usbcore(used by snd_usb_audio a snd_usb_lib) should I load some of these modules? or recompile the kernel with more things as module? PS: i tried to load for ex. snd-hwdep,snd,snd-rawmidi,snd-page-alloc,soundcore but they don't exist Thank you all, ale Alessandro Preziosi <lsnpreziosi(a)yahoo.com> wrote: I've tried to load snd-seq-midi and then use aseqdump -l but it still doesn't appear! I'd like to understand what's the problem... Maybe everything would work after a complete reinstall... Waiting for other hints...

I answer late, anyway this is the output of aseqdump -l: Port Client name Port name 0:0 System Timer 0:1 System Announce 14:0 Midi Through Midi Through Port-0 It doesn't appear :( Clemens Ladisch <cladisch(a)fastmail.net> wrote: Alessandro Preziosi wrote: Does it appear in the output of "aseqdump -l"? Regards, Clemens _______________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user Thanks for the help. Actually snd-seq-midi wasn't loaded. Anyway even after loading it with modprobe I did not see changes (tried to load before and after inserting the um-1s) This is my lsmod: (without snd-seq-midi) Module Size Used by snd_rtctimer 4640 1 ieee80211_crypt_wep 6272 1 snd_seq_dummy 4868 0 snd_seq_oss 30464 0 snd_seq_midi_event 8064 1 snd_seq_oss snd_seq 47184 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 8716 3 snd_seq_dummy,snd_seq_oss,snd_seq nvidia 6836340 22 snd_usb_audio 72928 0 snd_usb_lib 16128 1 snd_usb_audio sdhci 18572 0 mmc_core 26628 1 sdhci pcmcia 36524 0 ipw3945 106272 1 e100 33672 0 ieee80211 31944 1 ipw3945 ieee80211_crypt 6912 2 ieee80211_crypt_wep,ieee80211 i2c_i801 8588 0 i2c_core 21760 2 nvidia,i2c_i801 iTCO_wdt 11684 0 iTCO_vendor_support 4868 1 iTCO_wdt intel_agp 23836 1 serio_raw 7684 0 snd_hda_intel 20632 1 snd_hda_codec 153344 1 snd_hda_intel tifm_7xx1 8576 0 tifm_core 11268 1 tifm_7xx1 yenta_socket 25996 1 rsrc_nonstatic 13184 1 yenta_socket pcspkr 4096 0 joydev 10176 0 tg3 100484 0 e1000 112704 0 unionfs 70340 0 sl811_hcd 12672 0 ohci_hcd 19844 0 uhci_hcd 22928 0 ehci_hcd 29964 0 PS: I recently upgraded udev to version 108 (using gentoo) can this be linked to my problem (it didn't work before, but maybe with that module...)?
