[linux-audio-user] 2 questions ree: via vt8233

by Matt Price

Hi, running debian sid with a 2.4.18 kernel and alsa 0.9.5, I think. Folks on this list and alsa-user helped me get alsa working with my onboard sound, via vt8233, about a year ago. It works ok, but I've got 1 problem and one question. PROBLEM: every once in a while -- not often -- sound will hang and bring the whole system down; this happens with xmms, alsaplayer, and zinf, so I don't think it's strictly the playback software's fault. usually this isn't a catastrophe, since this is a workstation, not a heavy-duty server, but I'd like it not to happen. Anyone see this behaviour before, or know how I should try to diagnose it? QUESTION: My sound card has three analog outs (green, blue, pink). I gues sthese are for a 5.1 surround sound system or something, but I'd like to try to have one stereo out go to my cheapo speakers, and one go to my headphones. Unfortunately I'm unable to get a signal out of anything other than the pink out. The others just give static and wierd stuff, even with all the outputs turned up in alsamixer. Anyone know if it's possible to set this up the way I want? Even general hints abbout how 5.1 systems work would probably be really helpful. thanks loads, matt

Re: [linux-audio-user] Fedora and ALSA drivers.

by "horsh

Richard, For me it looks like your kernel has ALSA included into source tree already. It is only a guess -- I dont have a lny linux in hands right now but you can check it with something like: find /usr/src/linux/ | xargs grep -sqi alsa && echo yes I have ALSA in kernel NB: i haven't try this but should work horsh ==================8<=========================== Hallo, Richard hat gesagt: // Richard wrote: > This only 2 examples. > > gcc-3.3.1-6 > kernel-2.4.22-1.2097.nptl > kernel-source to match > > gcc -D__KERNEL__ -DMODULE=1 -I/home/ric/alsa-driver-0.9.7c/include -I/lib/modules/2.4.22-1.2097.nptl/build/include -O2 -mpreferred-stack-boundary=2 -march=athlon -DLINUX -Wall -Wstrict-prototypes -fomit-frame-pointer -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -pipe -DALSA_BUILD -DEXPORT_SYMTAB -c hwdep.c > In file included from /home/ric/alsa-driver-0.9.7c/include/sound/driver.h:42, > from hwdep.c:22: > /home/ric/alsa-driver-0.9.7c/include/adriver.h:134: error: redefinition of `PDE'/lib/modules/2.4.22-1.2097.nptl/build/include/linux/proc_fs.h:17: error: `PDE' previously defined here > make[1]: *** [hwdep.o] Error 1 > make[1]: Leaving directory `/home/ric/alsa-driver-0.9.7c/acore' > ... > At some point i been told that the drivers needed be fixed to compile in > fedora.so. well if you can make out something out of this.. ill appreciate Well, this is a bit strange. I'm guessing a bit now: The offending lines in your example result from adriver.h defining things for some kernel versions, including kernel 2.4.22. For example the error regarding PDE: /home/ric/alsa-driver-0.9.7c/include/adriver.h:134: error: redefinition of `PDE '/lib/modules/2.4.22-1.2097.nptl/build/include/linux/proc_fs.h:17: error: `PDE' previously defined here This means, that somewhere in "include/linux/proc_fs.h" the name PDE is already defined. In adriver.h ALSA tries to define it on its own like this: #if LINUX_VERSION_CODE < KERNEL_VERSION(2, 5, 4) #include <linux/fs.h> static inline struct proc_dir_entry *PDE(const struct inode *inode) { ... #endif The strange thing is, that in my rather vanilla version of kernel 2.4.22 there is no such thing as PDE in include/linux/*: $ grep PDE /usr/src/linux/include/linux/proc_fs* $ (nothing here) So I suspect, but I can only guess here, that your kernel source has a patch that introduces this PDE thing (I have no idea what it could be used for). I don't know if ALSA could fix that at all. It might be, that if Fedora ships a custom Linux kernel source, they should also provide adapted ALSA-sources. ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] How to check if I have midi connection?

by Ketil Thorgersen

Sorry about this extremely naive question, but since this is my first time trying to get linux to be a DAW I stumble onto some problems of course. And my know-how is somewhat limited unfortunately. My staudio c-port (envy 24 based 8 channel card analogue + 2 channel digital from www.staudio.com with built in midi-interface) works as far as audio goes now, but I can't seem to get anything out of the midiports even though it seems to be properly recognized. Alsa Patch bay gives me a: Rawmidi: 0 - Hoontech SoundTrack Audio DSP24 MPU-401 entry at least (actually 2 - one for each midi port), but no matter which I choose in rosegarden or any other app, I get no signal in the displays. How do I find out if it's working, and how do I troubleshoot. If this is well documented somewhere and comprehensible for semidummies, I'd be happy to receive a link! Best regards Ketil

Re: [linux-audio-user] How to check if I have midi connection?

by Taybin Rutkin

I believe the ALSA status page isn't as up-to-date as it should be. I would actually rely more on annecdote than it.

But the DSP24 as the base of the DSP2000C has been marked as "supported" in the sound card matrix since 2 years or so, even the ST Audio homepage says it?s supported, and now suddenly the ALSA guys tell us it?s even "untested". That?s what I call bad manners, at least. I never would have bought the DSP2000C with this status. FWIW, I?m a Linux user since 1994, as a Sysadmin I have moved the network in our university institute from Novell to Linux, for everything I do with a computer I use Linux (except music), so I am well aware of the problems and am willing to be patient, but this is definitely not the way I like it.

[linux-audio-user] on ALSA's virmidi module

by Dave Phillips

Greetings: I've been working with Tim Thompson's KeyKit, trying to get it to send its output to a softsynth. I can set a variable for KeyKit that will select the ALSA rawmidi device with this syntax : export ALSA_RAWMIDI_DEVICE=hw:1,0 where hw:1,0 refers to my card1 (the ALSA virmidi module) and its first device (0). Now when I start KK (and set the Port Enabler to ALSA) I can route its output to whatever connections are available via aconnect (or the kaconnect GUI). I just wanted to say "Thanks!" to the ALSA developers for the virmidi module. I've used it with MIDI sequencers running under emulation systems such as DOSemu and Xsteem, I've used it for the TK707 virtual drum machine, and now I'm using it with KeyKit. The combination of TiMidity-as-softsynth (with the Fluid soundfont) and the virmidi module is a very powerful and flexible system for me, and I just wanted to pass on a note of appreciation for the ALSA team's work. Okay, that's all. We now return to our regularly scheduled programming... Best regards, == dp

[linux-audio-user] Frustrated, but definately not giving up.

by Christopher Mazur

Does anyone know how to get RoseGarden4 and Ardour 0.9beta5 to play nicely? I thought that's why they added the JACK master/transport master function in Beta5 and I'd really like to have both of them synced. What I'm trying to do is not unlike using SMPTE have Rosegarden act as a slave and Rosegarden to be the master. Here's what I do: 1) Fire up Jack using QjackCTL 2) Load Ardour 3) Load Rosegarden I create a sequence in Rosegarden. Then nothing happens. :) I've gotten this far, but I can't get Ardour in Sync with Rosegarden when I press play in Ardour, rosegarden isn't "chasing" or locking onto sync. I'm trying to capture my sampler which is inputted to my Delta card and have the MIDI/Audio in sync. and no, I haven't been using MTC either.. I've noticed there is a Start|Pause feature in the qjackctl front end for JackD but It doesn't seem to have any effect. Is this configuring possible, or am I mistaken and just misinterpreting what the terminologies mean? If it's in fact just ardour and/or rosegarden has anyone been successful in syncing a MIDI sequencer and multi-track audio editor (MUSE/Audacity perhaps?) Regards, Chris

[linux-audio-user] please excuse my IDIOCY!!!

by Aaron Trumm

sometimes I can be such a damn cone head. I've sent this twice, letting it be in html form which I think will get rejected I hope y'all don't get three copies of it. -- Hello all - here's something I'm having a bit of trouble with, I thought y'all might know (hell it might've been in that huge mp3/ogg thread and I just missed it) I need to be able to rip hi res mp3s (320kbs) for submission to certain liscensing agencies (they insist) - but I haven't been able to figure out how to do this on my linux box. I know lame is the main backend - but I had some kind of trouble a couple weeks back either locating it or finding detailed info about it or something (I'm gonna go back and do this homework again), and then of course there's the matter of a front end, which I don't necessarily care about :) (but I remember not being able to figure out the proper command line commands or something) I had much success doing 128kbs mp3s - grip does it, audacity will just change a wav to an mp3, that's awesome, but they don't seem to deal with higher resolution than 128 - something made me think it's just not happening yet in linux and that I need to just rip them on my windows machine...was I right about this? I hope I didn't just miss someone talking about this on that long thread :) --------------------------------------------------------------- Houston Poetry Slam Team www.houstonpoetryslam.com NQuit Records www.nquit.com ---------------------------------------------------------------
