Hello everybody... And excuses for my bad english ;-) I have installed 64 studio this day. No problem with the installation on pIV 2.5 with 1 Go Ram memory. But it seems that the system dont see my roland Edirol UA 25 USB Sound card. I tries to resolve myself, but i'm e recent Linux user and i encountered some difficulties. I tried that: # lsmod | grep snd snd_usb_audio 76512 0 snd_seq_dummy 4996 0 snd_pcm_oss 40992 0 snd_mixer_oss 17280 1 snd_pcm_oss snd_seq_oss 32768 0 snd_seq_midi 9248 0 snd_pcm 73732 2 snd_usb_audio,snd_pcm_oss snd_seq_midi_event 8192 2 snd_seq_oss,snd_seq_midi snd_page_alloc 10760 1 snd_pcm snd_usb_lib 16768 1 snd_usb_audio snd_seq 48976 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 22148 2 snd_pcm,snd_seq snd_rawmidi 23712 2 snd_seq_midi,snd_usb_lib snd_seq_device 8972 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq,snd_rawmidi snd_hwdep 10116 1 snd_usb_audio snd 51300 12 snd_usb_audio,snd_seq_dummy,snd_pcm_oss,snd_mixer_oss,snd_seq_oss,snd_pcm,snd_usb_lib,snd_seq,snd_timer,snd_rawmidi,snd_seq_device,snd_hwdep soundcore 9056 1 snd usbcore 125832 8 snd_usb_audio,snd_usb_lib,usblp,usb_storage,usbhid,ehci_hcd,uhci_hcd You can see that module snd-usb-audio is running # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: UA25 [UA-25], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 The system sees the Edirol sound card # alsamixer No mixer elems found An in the task bar, at bottom right of my screen, the little speaker for volum control see a red cross, and doesn't want to run... I think it's not normal... If anybody seems something to do... Thanks in advance ;-)

I have found the solution! # cd /etc/iceweasel # gedit iceweaselrc And you must have this line: ICEWEASEL_DSP="aoss" If you use firefox: # cd /etc/firefox # gedit firefoxc FIREFOX_DSP="aoss" Close the file, close and re-open iceweasel, it's runnig properly, iceweasel is using aoss instead of alsa... Other softs runs properly with alsa, no modification!!! Simple isnt'it? ;-) Cheers Luc

To continue my researchs, i have resintalled Ubuntu in dual boot with 64Studio and i confirm that i have sound with all applications, and i have the sound with flash player. The extension of firefox on Ubuntu is the same as extension on IceWeasel on 64Studio... But for many reasons i want to stay with 64Studio (loaw latency Kernel, etc...) and impossible to make a correct install with Ubuntu studio :-(((((((((((((((((((( So this make me sure that it can run properly, but i don't understand the difference beetween the two installations... Thanks for help, and particularly for the 64Studio team, you do a really good stuff, really! Thanks Luc

The Flash player sends audio to your default windows device. There is no jack connectivity for it, so if you have only one sound device, you should stop jack to make your sound card available. Another alternative would be to have two sound cards, and to use the better one of the two for Jack and the other one as your default playback device. Cheers,

One more thing: I have no

Some things more, really strange: It seems sound runs properly, in Totem-Xine for example... So maybe it does'nt matter my little problems, but i continue thinking there is something wrong in my alsa configuration... If someone can give me a little help ;-) Thanks in advance Luc
