[linux-audio-user] Problems with Redhat 9(Shrike)

by Stewart Felstead

I’m attempting use the Shrike alsa rpm’s from fresh from to install alsa and it’s libs and utils. My pc is and athlon xp2000+ with an onboard via82c686 and am having problems getting alsamixer to launch. I keep getting the error no such device. My .asoundrc looks like this pcm.via82xx { type hw card 0 } ctl.via82xx { type hw card 0 } my modules.conf has this in it # OSS/Free portion - card #1 alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss # OSS/Free portion - card #2 (cmipci) alias sound-slot-1 snd-card-1 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-12 snd-pcm-oss I’m concerned that I need to disable the default Redhat sound stuff but have no as the system log shows errors trying to grab the port. But I have no idea how to do that. HELP!!!!!!!!!!! I’ve been struggling with this for weeks, and I’m getting pretty p$ssed off. Rgds Stew

Hi Ken: FWIW, my Linux Journal article on Linux software synths is now on-line: http://www.linuxjournal.com/article.php?sid=6320 It may help you get an idea of the state of things in May 2003...

I'm not surprised that noone reads laa.; Lots of people are crossposting their announcements to lau, and some even add lad to the list. If people would stop doing this, there would be incentive to read laa. -- Han-Wen Nienhuys | hanwen(a)cs.uu.nl | http://www.xs4all.nl/~hanwen

[linux-audio-user] Tracking down overruns

by Benji Flaming

Greetings all! I am attempting to initiate a long unattended 2-channel audio recording - perhaps lasting for an hour or two - but I am prevented from doing so by periodic overruns which occur at regular intervals. This interval changes according to my system configuration. Currently, I consistently get an overrun about 20 minutes after I start recording. My system is an AMD Athlon XP 1700+ with 256mb DDR266 memory. Video card is an ATI Radeon 7500/64mb. Sound card is an M-Audio Audiophile 2496. I'm running Slackware 9.0. My kernel version is 2.6.test5. Prior to this kernel I was using 2.4.21 with low-latency and preemptible kernel patches - with exactly the same overrun issue. I'm using jackd version 0.79.2, Ardour/GTK 0.378.0, and libardour 0.686.0 (all built from CVS source a few weeks ago.) I'm starting jackd with the command: jackd -v -a -R -d alsa -d ice1712 -r 44100 -p 2048 I don't want to clog everyone's mailbox with an even bigger message, so I've posted a bit of additional info online. Results from running latancytest0.42-png: http://www.comevisit.com/NorthernSunrise/latency/3x256.html http://www.comevisit.com/NorthernSunrise/latency/test2/3x256.html My .config file from my most recent 2.6.test5 kernel build: http://www.comevisit.com/NorthernSunrise/latency/.config My jack, and ardour version numbers, and hdparm info for hda and hdb: http://www.comevisit.com/NorthernSunrise/latency/configuration I can see from the latency tests that *something* is causing spikes, particularly during disk write, but I'm not sure how to determine precisely what it is. Is there any way to obtain a snapshot of processor usage at the exact moment of an overrun? Any help or advice (or reminders about what info I've neglected to give) would be very much appreciated! |) |)enji Benjamin Flaming -------------------- "The trouble with computers, of course, is that they're very sophisticated idiots."

[linux-audio-user] Compile shaketracker

by Gerrit Niestijl

Hi, A few months ago someone on this list managed to compile shaketracker with gcc-3.x. He offered to make a patch if anyone was interested. Is that offer still valid? I am on redhat 9 (planet), and i have no skills to get there myself. I also would like to try ttrk, but this one also fails to compile on my box. Any help would be greatly appreciated! -- Gerrit

[linux-audio-user] RME hammerfall DSP Multiface: help needed

by Robert Epprecht

I'm having a hard time bringing my new RME pci interface and Multiface to run... and would appreciate some help ;-) I'm working on Debian/unstable, have compiled the kernel with lowlat and preempt, installed ALSA, inserted the hdsp modul, made a basic ~/.asoundrc, compiled hdsploader from alsa-tools and with the friendly help of Thomas Charbonnel also hdspmixer. hdsploader loads the firmware (well it does the *second* time I run it, which is a known problem, as Thomas told me). The error LED on the Multiface is off. Input (on analog input1) *does* show in hdspmixer (only in the *input* channel, nowhere else), but I can't get any sound. Hmm, here I have the first question: Do I have to run alsamixer or hdspmixer or both to unmute the channels? (I have tried all of this). I have tried to feed a signal to analog input 1 and get it out from analog output 1. I have also tried to set the internal routing with amixer, but don't know if I have done that right... Well, the doc says hdsp defaults to route inputx to outputx anyway. But I can't hear anything... I have tried 'cat some.wav > /dev/dsp' no sound, no errors. (where would the error message show up?) I do hear a high pitched hiss on line out, nothing else. Please tell me: What would be the most basic procedure that should produce sound output on the Multiface? What diagnostic information can I give you to find out why it is not running yet? Thanks a lot for any hints! Robert Epprecht

[linux-audio-user] Message about Ardour(the last?)

by Alexander

Hi! Finaly I can run jackd and compile Adour. But I can't run Ardour. I can see the splash screen, but Ardour killing itself. So: # ardour Ardour/GTK 0.380.1 running with libardour 0.686.3 Loading UI configuration file /usr/local/ardour/ardour_ui.rc Loading system configuration file /usr/local/etc/ardour/ardour_system.rc Loading user configuration file /usr/local/etc/ardour/ardour.rc ardour: [WARNING]: MMC MIDI port "trident" not available: no MMC control possible 343: received signal 4 ardour is killing itself for a clean exit Killed I don't get Ardour using CVS because I can't connect the cvsroot. So, I get the file ardour_current-cvs.tar in the website of Ardour. What is MIDI port "trident"? I haven't hardware trident, any, in my computer. The TODO file say: "don't initiate MIDI binding if there is no MMC control". Is it my answer? But where I disable "MIDI binding"? I don't make any change in the files *.rc But after this error I remove any line about MMC or MIDI and I get the same error. Somebody can help me? Thanks! Alexander

Re: [linux-audio-user] YMFPCI hardware midi/snd-mp401-uart Problem

by BartonBosch＠aol.com

snd-mpu401-uart is the driver for the external MIDI port (you'd need a gameport/MIDI adapter for this). snd-rawmidi is an ALSA module handling device file management and buffering for MIDI ports. snd-opl3-lib is the driver for the OPL3 FM synth. Thanks, got it. So if I wanted to deal with the FM sound quality I could use the legacy synth? I guess Muse uses the ALSA sequencer. Run "aconnect -o" to see a list of output ports. This is the output of aconnect -o when both TiMidity and MusE are running: [barton@localhost barton]$ aconnect -o client 128: 'Client-128' [type=user] 0 'TiMidity port 0 ' 1 'TiMidity port 1 ' client 129: 'MusE Sequencer' [type=user] 0 'MusE Port 0 ' >Checking /proc/asound/devices does not list any midi devices, Did you specifiy the parameters for snd-ymfpci in modules.conf? (e.g. mpu_port=0x330 fm_port=0x388) No I didn't. So to use alsa with the midi port that is on the motherboard I would need to configure the memory address mpu_port=0x330 in /etcmodules.conf? Does the line need to go in a specific place, and is that the exact syntax? Is this documented somewhere? I have installed alsa manually on this machine before (this time I used the Planet RPMs and alsaconf) and I don't remember seeing anything that referrred to memory addresses for the midi ports. Thanks, Barton
