I'm trying to get my Roland UM-2 usb to midi interface working on the 2.6.4 kernel. I have the kernels usb midi and usb audio turned off. The alsa usb audio driver is a module. I can access the device via /dev/midi01 meaning if I cat a midi file the lights on the interface blink. What I can't do is have Alsa see it. I would like to be able to use this device under rosegarden or pmidi . Any ideas as to what I'm doing wrong. /var/log/messages/ Mar 14 07:55:08 Kesh kernel: usb 3-1: new full speed USB device using address 2 Mar 14 07:55:09 Kesh kernel: snd-usb-audio: probe of 3-1:1.0 failed with error -5 Mar 14 07:55:09 Kesh kernel: snd-usb-audio: probe of 3-1:1.1 failed with error -5 Mar 14 07:55:09 Kesh kernel: ALSA sound/usb/usbmidi.c:531: switching to altsetting 1 with int ep Mar 14 07:55:09 Kesh kernel: ALSA sound/usb/usbmidi.c:782: created 2 output and 2 input ports [root@Kesh asound]# ls /proc/asound/ -l total 0 lrwxrwxrwx 1 root root 5 Mar 14 09:53 Snapper -> card0 lrwxrwxrwx 1 root root 5 Mar 14 09:53 UM2 -> card1 lrwxrwxrwx 1 root root 5 Mar 14 09:53 VirMIDI -> card2 dr-xr-xr-x 4 root root 0 Mar 14 09:53 card0 dr-xr-xr-x 2 root root 0 Mar 14 09:53 card1 dr-xr-xr-x 2 root root 0 Mar 14 09:53 card2 -r--r--r-- 1 root root 0 Mar 14 09:53 cards -r--r--r-- 1 root root 0 Mar 14 09:53 devices -r--r--r-- 1 root root 0 Mar 14 09:53 meminfo dr-xr-xr-x 2 root root 0 Mar 14 09:53 oss -r--r--r-- 1 root root 0 Mar 14 09:53 pcm dr-xr-xr-x 2 root root 0 Mar 14 09:53 seq -r--r--r-- 1 root root 0 Mar 14 09:53 timers -r--r--r-- 1 root root 0 Mar 14 09:53 version [root@Kesh /]# cat /proc/asound/oss/sndstat Sound Driver:3.8.1a-980706 (ALSA v1.0.2c emulation code) Kernel: Linux Kesh 2.6.4 #12 Sat Mar 13 20:33:42 PST 2004 ppc Config options: 0 Installed drivers: Type 10: ALSA emulation Card config: PowerMac Snapper (Dev 35) Sub-frame 0 EDIROL UM-2 at usb-0001:01:1b.0-1 Virtual MIDI Card 1 Audio devices: 0: PowerMac Snapper (DUPLEX) Synth devices: NOT ENABLED IN CONFIG Midi devices: 1: UM-2 2: Virtual Raw MIDI Timers: 7: system timer Mixers: 0: PowerMac Snapper 1: mixer10 2: mixer20 [root@Kesh src]# aconnect -lo client 80: 'Virtual Raw MIDI 2-0' [type=kernel] 0 'VirMIDI 2-0 ' client 81: 'Virtual Raw MIDI 2-1' [type=kernel] 0 'VirMIDI 2-1 ' client 82: 'Virtual Raw MIDI 2-2' [type=kernel] 0 'VirMIDI 2-2 ' client 83: 'Virtual Raw MIDI 2-3' [type=kernel] 0 'VirMIDI 2-3 '

Re: [linux-audio-user] ppc audio input..

It is normal that the status has closed unless you are actually recording. My G4 titanium uses the snapper chip, so we use the same kernel driver. What do you have in /proc/asound/devices? I get: 1: : sequencer 0: [0- 0]: ctl 16: [0- 0]: digital audio playback 24: [0- 0]: digital audio capture 33: : timer If you get a similar entry for capture, we should be able to get it going. Make sure your "PCM 1" and "Monitor" entries are turned up in your mixer. Like Derek I also have a lot of noise problems, but my best results so far are with PCM 1 set to 75%-85% and Monitor set to 90%. I'm still puzzled how these two relate. > on the flipside, os9 has no problems with sound input, which leads > me to suspect that it has control of an internal setting that linux > does not.. Hmm, haven't checked out the Mac OS side yet.

You could try a friendly mail to: linuxppc-dev(a)lists.linuxppc.org I'm using the PPC specific kernels from: http://penguinppc.org/dev/kernel.shtml so far with the same results you get (the 2.5 tree realy holds the 2.6 kernel now). But any fixes will be in here first. Martin

Re: [linux-audio-user] [Fwd: Edirol FA-101 Linux Support]

by Martin Habets

> From: Dan Harper <tech(a)danharper.org> > > I just sent this e-mail to Edirol. It may be useful to someone if > they're contacting them or any other company for Linux support. > > > Dan The FA-101 is based on the BridgeCo BEBOB, like a number of other products from Apogee, Tascam and Presonus that were presented at NAMM. If we could get support from one of these vendors it should be (relatively) easy to get them all working. People also talked about the M-Audio FW410 on this list before. I know it uses the DM1000 inside. Anyone know if FW410 is also based on BEBOB? Is anybody in touch with BridgeCo, or any info wrt their stand on Linux? But all this won't get us around the Yamaha connection management issue, will it? Martin http://www.bridgeco.net/products/bebob/bebob.shtml

[linux-audio-user] LilyPond interview on linuxmusician.com

by Chris Cannam

A quick note to say that I've just put together an interview with Han-Wen Nienhuys and Jan Niewenhuizen, of the LilyPond project, and it's now at http://www.linuxmusician.com/ . The interview is pretty long and covers quite a few subjects, and I think is a very interesting read. I'm very grateful to Han-Wen and Jan for doing almost all of the hard work. Chris

Re: [linux-audio-user] Kernel 2.6.x latency

by Sampo Savolainen

Thank you for the config. I'll try building on that. I see you have the security capabilities on. Do you use the realtime module I was talking about? Or do you use the capability/commoncap in a special way? Are there some module parameters I should give to capability or commoncap?

[linux-audio-user] OT: cannot reach ardour.org

by Robert Epprecht

I know it is quite OT, but I have tried many other ways to solve the problem. Since ardour moved away from sourceforge I try to reach ardour.org and lists.ardour.org, but I can't. While list post from ardour-users did reach me for some time I got a message that I have been unsubscribed due to bounces. Whatever I try to reach them (confirmation mail, contacting listmaster, http, ping) gives me only errors. I have tried for more than two weeks now, but never reached them... I have no idea what might be wrong. Maybe ardour is on a blacklist or something? BTW: I'm living in Switzerland if that could matter. Can someone give me a *working* ardour URL or the IP of ardour.org or lists.ardour.org or any other help to solve the problem. Thanks a lot and forgive me to be off topic, Robert Epprecht

[linux-audio-user] Audio distortion with DMA enabled

by adam

Hi, I'm having problems with sound on my pc - a crackling sound. This only occours when DMA is turned on and there is ide disc access. It seems to be independent of the DMA speed. Also there is the same problem in windows with the manufacturers drivers. Here are my PC specs: Motherboard: Gigabyte GA-7VRXP Chipset: VIA KT333 / VIA VT8233A Onboard sound: Creative CT5880, Sigmatel 9721T CODEC (using alsa ens1371) I have also tried out another sound card (but with the same driver) with the same problems. I have heard that a BIOS PCI Latency setting can help this problem but cannot see this option in my bios. Thanks, Adam
