[linux-audio-user] alsa clients plugged into jackd with jackplug

by Esben Stien

I don't think I understand this jackplug concept. I'm trying to get an alsa client, such as aplay to play through jackd. I've setup jackplug in /etc/asound.conf pcm.jackplug { type plug slave { pcm "jack" } } pcm.jack { type jack playback_ports { 0 alsa_pcm:playback_1 1 alsa_pcm:playback_2 } capture_ports { 0 alsa_pcm:capture_1 1 alsa_pcm:capture_2 } } I then tell aplay to use: #aplay -d jackplug foobar.wav But aplay plays the file even if jackd is not started; why?. Isn't jackplug supposed to show up in my jack connections when aplay is playing? I seem to be missing something vital. Is there some way to make a "fake audio device", like hw:3,0 that alsa applications can connect to so that I can get the audio out and then send it through jack, process it and then send it to the real audio device? -- Esben Stien is b0ef(a)esben-stien.name http://www.esben-stien.name irc://irc.esben-stien.name/%23contact [sip|iax]:b0ef@esben-stien.name

There are a few alternatives. Not much that I have on Windows or Linux support clock messages. MagicBaton was a MIDI-player that added events based on the mouse-conducting. Alternatives: 1. Run the Boa in Parallel with whatever sequencer or player is going through jack or such. Boa would then put out simply omni/overall level and tempo events. 2. Run Boa as a plug-in Rosegarten, Muse or other such program. In this case, it would work on one track/channel and insert expression (and tempos) or in an omni mode as above. For rehearsing (MagitBaton's parlance) one track, one would probably want to disable tempo changes and conduct expression. Omin/overall would do level and tempo. 3. Controlling another software via midi-clock and some volume control device. This assume, naturally, that this software is available :-)

[linux-audio-user] Behringer BCA 2000 - has anyone tried it ?

by Jan Holst Jensen

Hi. I see that Behringer has released a new gadget: http://www.behringer.com/BCA2000/index.cfm?lang=ENG Has anyone tried this thing ? Does it work with the generic USB audio driver or do we have to wait for ALSA drivers to become available ? I am _almost_ off to buy one :-).

by Ryan Gallagher

I think I may have screwed up the threading with my last post... but eh, gives me the chance to include two more tunes I've done lately. More circuit-bent casio, some samples in hydrogen all edited together in ardour.

hello! i post to linux-audio-user instead of -announce i fixed the missing kluppe.png and uploaded a new tarball (0.4.1) being kicked off by jack is bad. low latencies are hard to test for me, because my hardware forces me to run -p 1024 or even -p 2048. is there any difference between 0.3 and 0.4 for you? is there any specific situation (e.g. loading files or opening new loopers) that results in kluppe being dropped by jack? regards d13b Esben Stien wrote: > d13b <kluppe(a)klingt.org> writes: > > >>kluppe 0.4 is out > > > I have to run with extremely high latencies to have it work without > being kicked off by jack (-p 1024).

[linux-audio-user] SB Live! 24-Bit & CA0106

by Edward Deards

Hi all, I'm new to the list, so be gentle. Trying to get a Creative Sound Blaster Live! 24-Bit functioning for a friend many many thousands of miles away. I found one moderately useful thread archive from this list, and it seems he who wrote the CA0106 ALSA driver module is on here. After a lot of stuffing about I discovered that the ca0106 was needed, not the emu10k1, much to my irritation. Eventually I upgraded the lad's kernel from 2.6.3 to 2.6.11 but just downloading the source and compiling it up. In addition I replaced all the ALSA user-space stuff with version 1.0.6 packages using assorted redhat rpms, as Mandrake appears as old as the hills re ALSA. Now I've got the card recognised... and things seem to believe they are playing fine. However there is no sound. The little gnomes in the back of my head shouted "it's the volume, it's the volume.. unmute something". However all volumes I can affect in alsamixer are now set to maximum. The remaining controls are all read only. What concerns me is that notable controls are missing, such as Master Volume and PCM Out. If I saw either of those I'd feel happier. I could attach the /etc/alsa.state file if it would assist anyone in seeing the probably obvious. Does anyone have an idea? Finally, if this is indeed completely the wrong place to post this, tell me so and I shall flee. I have however spent a long while rtfming the available sources, to little avail beyond getting the card noticed. Cheers, Edward

[linux-audio-user] alsa hdsp and oss emulation

by peter plessas

Dear list, this is a bit complicated, due to big/little endian issues, perhaps. I am trying to load the firmware into my hdsp pcmcia card. I am getting the fifo timeout: peter:~# hdsploader hdsploader - firmware loader for RME Hammerfall DSP cards Looking for HDSP + Multiface or Digiface cards : Card 0 : PowerMac Screamer Rev 0 Card 1 : RME Hammerfall DSP at 0xf3000000, irq 58 Upload firmware for card hw:1 Hwdep ioctl error on card hw:1 : Input/output error. I am using debian testing, running a 2.6.8 kernel with manually compiled 1.0.8 alsa drivers on a G3 powerpc laptop. cardbus version is 11 (rev 0b) the card is loadable out of osx. i am stuck here, and don't know what to do now. any suggestions are very welcome! thanks, Peter

hi i am using gentoo linux with 2.6.9 amd64 kernel alsa driver 1.0.7-rc3, firmware 1.0.6 and utils 1.0.7 hdsploader and hdspconf works unmuting using amixer and aplay works too but hdspmixer crashes: HDSPMixer 1.6 - Copyright (C) 2003 Thomas Charbonnel <thomas(a)undata.org> This program comes with ABSOLUTELY NO WARRANTY HDSPMixer is free software, see the file COPYING for details Looking for HDSP cards : Card 0 : NVidia CK8S with ALC850 at 0xeb001000, irq 11 Card 1 : RME Hammerfall DSP + Multiface at 0xea000000, irq 10 Multiface found ! 1 Hammerfall DSP card found. Initializing default presets Segmentation fault i think i have read something about a fix for 64bit regarding hdsp things in alsa 1.0.7-rc2 ... so i must have it allready? i dont know if i should use alsa 1.0.8 because it is marked unstable for amd64 in gentoo portage ps: i would be thankful if someone can tell me how to search this mailing list if possible -- ___________________________________________________________ Sign-up for Ads Free at Mail.com http://promo.mail.com/adsfreejump.htm

[linux-audio-user] USB-audio-card notches

by Christoph Eckert

Hi, it's easter time, so I play a bit with aeolus ;-) . Anyway, I have a Dell Inspiron 8200 with a vanilla 2.6.10 kernel. The only patch applied is the LSM-RT-patch. The Inspiron offers a USB 1.1 port. A USB 2.0 hub is connected to it. On the hub, there are currently two USB devices: * A Midisport 8x8 * A Terratec Aureon 5.1 USB On top of the card, I start JACK. I tried various settings, currently I use /usr/bin/jackd -v -R -P5 -p16 -t2000 -dalsa -dplughw:2 -r48000 -p256 -n3 -P As soon as I play through JACK, I get notches, regardless if it was alsa modular synth, Aeolus or xmms. The log shows lines like the ones attached below. So I stopped JACK and tried to use the device in ALSA only mode. * xmms now plays fine on the device hw:2,0 * ams and aeolus produce a lot of xruns and I get no audio output using hw:2,0 * when starting ams as ams --soundcard plughw:2,0 --rate 48000 I get a lot of xruns again and the sound is worse (more notches) as when running ams or Aeolus on top of JACK * notches also appear as soon as I try to record audio input using qarecord connected to JACK * when using plughw:2,0 and a samplerate of 48000 (44100 will not work) in the aeolusrc, I get proper output at least by Aeolus I could need a helping hand by making the card working properly. Anyone an idea where I can put the screwdriver? I did also have a look into the modinfo of snd-usb-audio, but I cannot detect a parameter to tell it, mybe, to use a samplerate of 48000 or similar settings: modinfo snd-usb-audio author: Takashi Iwai <tiwai(a)suse.de> description: USB Audio license: GPL parm: index:Index value for the USB audio adapter. parm: id:ID string for the USB audio adapter. parm: enable:Enable USB audio adapter. parm: vid:Vendor ID for the USB audio device. parm: pid:Product ID for the USB audio device. parm: nrpacks:Max. number of packets per URB. parm: async_unlink:Use async unlink mode. vermagic: 2.6.10ce SMP PENTIUMII 4KSTACKS gcc-3.3 depends: snd-usb-lib,snd-pcm,snd Every wee small hint (even RTFM ;-) is much appreciated.
