[linux-audio-user] S/PDIF input on M-Audio Dio2448

by Anahata

Believe it or not, I've only just (bothered to) get ALSA working on my system (Debian Sarge snapshot a couple of months old) I have a M-Audio DiO 2448, and the primary reason for choosing it was for S/PDIF digital input. That worked with the OSS drivers (paid for...) - now how do I control the S/PDIF input with ALSA? The driver module is snd-cmipci. -- Anahata anahata(a)treewind.co.uk -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827

[linux-audio-user] edirol um-880 configuration help needed

by Chris Pickett

Hi Clemens (or others, if you can help), I am trying to get my Edirol UM-880 to work with Rosegarden-4.0.9.7 and alsa-1.0.4. This is a rackmount USB 8x8 MIDI interface. I have a gentoo-2.6.5-r1 kernel with USB support compiled in. ------------------ /usr/src/linux # grep -i midi .config CONFIG_SND_RAWMIDI=y # CONFIG_SND_VIRMIDI is not set CONFIG_USB_MIDI=y ------------------ The first thing I noticed is that it doesn't work with the default Edirol driver, about which the manual says: ------------------ FPT technology will be used to perform high-speed MIDI transfer. We recommend that you normally use this mode. FPT = Fast Processing Technology of MIDI Transmission -- this optimizes MIDI data processing by making efficient use of the USB bandwidth according to the amount of MIDI data being transferred. ------------------ I get the following in /var/log/messages when I plug in a USB cable with this driver enabled in the hardware: ------------------ usb 1-1: new full speed USB device using address 2 midi: probe of 1-1:1.0 failed with error -5 ------------------ To change this, you have to follow the instructions in the manual to use the generic driver mode. Ok, fine. I'm guessing Edirol isn't likely to release specs for the fancy one, but I haven't gone about asking. Now /var/log/messages shows me: ------------------ usb 1-1: new full speed USB device using address 3 usb-midi: Found MIDISTREAMING on dev 0582:0015, iface 0 usb-midi: Found MIDIStreaming device corresponding to Release 1.00 of spec. usb-midi: Found IN Jack 0x10 EMBEDDED usb-midi: Found IN Jack 0x11 EMBEDDED usb-midi: Found IN Jack 0x12 EMBEDDED usb-midi: Found IN Jack 0x13 EMBEDDED usb-midi: Found IN Jack 0x14 EMBEDDED usb-midi: Found IN Jack 0x15 EMBEDDED usb-midi: Found IN Jack 0x16 EMBEDDED usb-midi: Found IN Jack 0x17 EMBEDDED usb-midi: Found IN Jack 0x18 EMBEDDED usb-midi: Found IN Jack 0x20 EXTERNAL usb-midi: Found IN Jack 0x21 EXTERNAL usb-midi: Found IN Jack 0x22 EXTERNAL usb-midi: Found IN Jack 0x23 EXTERNAL usb-midi: Found IN Jack 0x24 EXTERNAL usb-midi: Found IN Jack 0x25 EXTERNAL usb-midi: Found IN Jack 0x26 EXTERNAL usb-midi: Found IN Jack 0x27 EXTERNAL usb-midi: Found IN Jack 0x28 EXTERNAL usb-midi: Found OUT Jack 0x30 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x31 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x32 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x33 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x34 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x35 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x36 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x37 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x38 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x40 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x41 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x42 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x43 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x44 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x45 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x46 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x47 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x48 EXTERNAL, 1 pins string descriptor 0 found (length = 4) usb-midi: langid(0) 0x0409 usb-midi: langid(match) 0x0409 usb-midi: fetchString(2) usb-midi: fetchString = 13 usbmidi: found [ EDIROL UM-880 ] (0x0582:0x0015), attached: usbmidi: /dev/midi01: in (ep:81 cid: 0 bufsiz:64) out (ep:01 cid: 0 bufsiz:64) usbmidi: /dev/midi02: in (ep:81 cid: 1 bufsiz:64) out (ep:01 cid: 1 bufsiz:64) usbmidi: /dev/midi03: in (ep:81 cid: 2 bufsiz:64) out (ep:01 cid: 2 bufsiz:64) usbmidi: /dev/midi04: in (ep:81 cid: 3 bufsiz:64) out (ep:01 cid: 3 bufsiz:64) ------------------ Which looks a lot more promising.

If I disconnect the USB cable, there is no change in the rosegardensequencer messages. alsa-patch-bay doesn't show me the UM-880 either, and there is no change with or without the cable connected. Finally, '/etc/init.d/alsasound restart' doesn't fix things. So ... what am I missing here? I looked in various places but couldn't find any information about what I need to do. Cheers, Chris

[linux-audio-user] Realplay 8.0 and sfxload; life is strange

by Marv Smoak

On my system, I using Planet CCRMA vintage March 2003. Realplay version 8.0.3.421 and sfxload version 0.4.3; when I need to boot my system, I must follow the procedure below to get realplay to work when I load a soundfont to my sblive card. Today I had to re-discover this sequence for the N-th time so I wrote it down. I'm posting it here in hopes it will help someone; I don't understand why it works, but it does, on my system. How to get realplay to work after using sfxload to load a soundfont to a SB-Live card. (Assume you've done a reboot of system, logged in as a user to KDE.) 1-- Before using sfxload, start realplayer first. Connect to internet and open a location such as http://www.jazz.fm/liveg2.ra ; realplay plays the stream. 1.1-- I usually start AlsaPatchBay and AlsaMixer at this point; it doesn't seem to matter whether this is done at this stage or later. 2-- While realplay is playing the stream, load the soundfont; on my sys sfxload 4marv/soundfonts/FluidR3_20GM.SF2 On my sys, the stream must be playing. During the loading of the soundfont the stream playing stops and and realplay says "Buffering". After the font is loaded, hit the stop button on realplay and re-connect to the location. The stream will start playing again. After this sequence, I can quit out of realplay and restart is without getting the dread "cannot open the sound device..." message. If realplay is not up and actively playing a stream when sfxload loads the soundfont, realplay will not find the sound device. And my system must re-booted. Logging out and back in, does not work. The soundfont load does not survive the boot.

Crawford >GoingWare Inc. - Expert Software Development and Consulting >http://www.goingware.com >crawford(a)goingware.com Michael, Thank you for your article. If I can ever get myself to concentrate long enough to get my own site online I will be linking to yours. I've long felt that music should be something that everyone has the right to _do_ themselves. The experience of making sounds happen seems to me to be something everyone needs. So many people do not get this experience. My knowledge of history may be a bit spotty, but in general my understanding is that before the rise of the Music Business a far greater percentage of the population actually participated in music making fairly regularly rather than merely consuming entertaiment. Now it seems to me that most people in the general population are afraid, or can't even conceive, of making music themselves. The feeling I get is that the average person (amongst the general population -- not the average reader of this list :) ) is trained to think that if they can't sell millions of albums they might as well not bother. This is a horrible shame. My personal hope is that the internet and free software can help to give back to the individual the freedom to create and to enjoy the act of creating. The world will be a better place for it. Thank you again. You have stirred me up a bit, definitely for the better :) -Eric Rz.

Nothing about that store is tempting. Unfortunately my lack of disposable income limits my options to the least expensive equipment. > Well, ECS motherboards are at the bottom of the > barrel.

I have read conflicting reports re: those boards for general desktop usage, some say they are rubbish, others say that they offer the best value. I figured I'd ask the list for some linux audio specific info. > I know I > found my ECS Pentium 4 motherboard to be barely > adequate and that was just > for a TELEPHONY logging application where I could > tolerate a -65 dB noise > floor. (OUCH) I guess I should have mentioned that I am not building a DAW for a home studio or anything. I mentioned that my current machine is a PIII-550 without room for any significant upgrades. It is more or less sufficient for most of what I am doing (word processing, telecommunicating, web development, etc.) but for the bits of audio that I am doing it is a little slow. E.g., remastering field recordings with Jamin is a big hassle and completely ties up the computer. I am not doing any 24 bit recording on this box or anything, no analog signals being recorded at all really so RFI or whatever causes the noisyness shouldn't be that relevant (or should it?). > The K7VTA3 is a VIA-chipset system with all of the > usual vagaries and bugs > implied thereto. Okay, so the VIA chipset is problematic re: audio? Could someone who has experienced this briefly outline the problem or maybe point me toward some documentation? > The N2U400 is an nVIDIA nForce chipset motherboard, > which === message truncated === [that's what I get for using my backup webmail interface w/ lau in digest mode I guess] So the upshot is that the nVIDIA chipset is significantly better than the VIA board? Because it is also 40% more expensive as well. But if it really offers a better value then I might go for it. Any informed opinions? Thanks, Barton __________________________________ Do you Yahoo!?

[linux-audio-user] New version of desktop sounds now available

by Ivica Bukvic

I guess the title says it all. You can grab it from the same place: http://www.kde-look.org/content/show.php?content=12584 (the download is a bit of a hog for the time-being due to fact that I've included 7 different versions of the startup sound in hope users can help me figure out which one is the best one) Comments, questions, and obviously votes are most welcome! Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico
