[linux-audio-user] Delta 44 ... more troubleshooting

by reuben

Apologies for not staying in thread, but when I reply my messages get held for approval (I have suspicious headers??) To recap: I have a delta 44. lsmod shows that the ice1712 driver is correctly loading. Both kmix and envy24control show all channels etc. However, I don't seem to be able to output to it using ALSA. (In envy24control, the meters never show activity; in xmms, which I am using as a step 1, anything I try results in "are you sure you card is configured"...) Could somebody guide me through the ALSA settings that work for them for, e.g. xmms? Thanks Reuben

[linux-audio-user] Transposing an MP3 file

by Peter Clarke

Hi all, My first post here. Terrence asked about transposing an MP3 file, and Erik's reply is correct in that you can transpose it by resampling, provided you can put up with the music changing speed as well - which is, of course, usually not acceptable. However, Audacity has a transpose function. It's in the Effects menu, called "Change pitch". I haven't tried it with music, but it works great with speech - making the voice deeper without slowing it down.

[linux-audio-user] Transposing, revisited

by Terrence

Hello, all, I'd asked about a program for transposing midis, but have found an MP3 that's even better. Is there a console program that will transpose MP3s? Thanks, Terrence

[linux-audio-user] ALSA issues

by Christoph Eckert

Hi all, I have some ALSA issues around for ages and I'd like to ask for help. I'm running a Gentoo box and just updated to a vanilla 2.6.14.2 with no further patches applied. I even updated ALSA to 1.0.10rc1. I'm using the kernel drivers, no external drivers installed. JACK was taken from CVS some time ago and is version 0.100.0, tmpdir /dev/shm installed. I run an internal AC '97 chip (with modem functionality), a Terratec USB audio device, a Midisport 8x8, a m-audio Trigger Finger USB-MIDI device and (occasionally) an Edirol UM-1S. The firmware for the Midisport gets loaded via hotplug (very cool script BTW, thanks to the author) as well as snd_usb_audio gets loaded by hotplug. Now the issues: I.) According to http://alsa.opensrc.org/MultipleCards I tried to set the cards to a certain order because I'd (mainly) to see the Terratec card with the same number each time I log in. Unfortunately this doesn't work. I have included the content of the file /etc/modules.d/alsa at the end of this mail. The path to this file is Gentoo specific, but at least alsaconf uses it to enter it's entries. I wanted the internal AC '97 card to be the first one and the default for desktop use, but the ordering is as follows: 0 [Audio ]: USB-Audio - USB Audio USB Audio at usb-0000:00:1d.2-1.3, full speed 1 [Finger ]: USB-Audio - USB Trigger Finger M-Audio USB Trigger Finger at usb-0000:00:1d.2-1.4, full speed 2 [I82801CAICH3 ]: ICH - Intel 82801CA-ICH3 Intel 82801CA-ICH3 with CS4205 at 0xd800, irq 11 3 [Modem ]: ICH-MODEM - Intel 82801CA-ICH3 Modem Intel 82801CA-ICH3 Modem at 0xd400, irq 11 4 [M8x8 ]: USB-Audio - MidiSport 8x8 M-Audio MidiSport 8x8 at usb-0000:00:1d.2-1.1, full speed Any hint would be really appreciated. II.) When doing an /etc/init.d/alsasound restart, all cards are lost. cat /proc/asound/cards tell me "no cards". I get back my USB devices as soon as I replug them thanks to hotplug, but the internal card is lost until I reload the modules manually *or* reboot the machine. There seems to be some magic, or does the boot process additional things except invoking /etc/init.d/alsasound?!? III.) Formerly I did loadthe snd_usb_audio module in /etc/conf.d/local.start so I could pass some parameters to improve USB audio latency: modprobe snd-usb-audio nrpacks=1 What is the right place now as the module gets loaded via hotplug? None of these problems is urgent, but I'd really like to know why my setup doesn't work as expected ("Computer, do what I want!" :) so any wee small hint would be great.

[linux-audio-user] kernel-2.6.14.2-lsm only slightly better...

by thewade

Hi again! I built and installed 2.6.14.2. Like the standard FC4 kernel on this machine I had to disable acpi - I don't know if that could hurt anything besides battery performance... I built and installed realtime-lsm-0.1.1, running it with modprobe gid=500 any=1. I built jackd using: --with-default-tmpdir=/dev/shm (Fedora's tmpfs ram device, or so I think) (BTW: my fstab is weird about jacks temp directory (# This file is edited by fstab-sync - see 'man fstab-sync' for details (LABEL=/ / ext3 defaults 1 1 (LABEL=/boot /boot ext3 defaults 1 2 (/dev/devpts /dev/pts devpts gid=5,mode=620 0 0 (/dev/shm /dev/shm tmpfs defaults 0 0 (/dev/proc /proc proc defaults 0 0 (/dev/sys /sys sysfs defaults 0 0 (LABEL=SWAP-hda5 swap swap defaults 0 0 (none /dev/shm tmpfs defaults 0 0 (/dev/hdc /media/cdrecorder auto pamconsole,exec,noauto,managed 0 0 (none /dev/shm tmpfs defaults 0 0 --enable-capabilities=0 (I thought this was bad 'cause the ccrma jack.spec file as capabilities disabled. Same results with enabled) --enable-posix-shm --disable-oss The best I can do with jack without out more then the 13 initial XRUNS is: /usr/local/bin/jackd -R -P70 -u -dalsa -dhw:0 -r48000 -p256 -n2 -m -H -M ...though qjackctl says cannot use real-time scheduling (FIFO at priority 69) [for thread -1211757648, from thread -1211757648] (1: Operation not permitted) cannot lock down memory for RT thread (Cannot allocate memory) the qjackctl statistics window says realtime is enabled. When I run PD I use nice -5 pd but at the above frames/period I get all kinds of static when I change or move windows. I have to go back to -p1024 to avoid thoes pops (A/D/A sync errors PD calls them) So I guess I am ready to try changing the IRQ's of my sound cards (Mark?) . What should I do to make my machine perform better? I am going to ask the pd-list about pd optimizations. Thanks! -thewade

Re: [linux-audio-user] kernel-2.6.14.2-lsm only slightly better...

by thewade

So the weirdest thing just happened: I got tired of trying to figure out why the realtime module wasn't working so i started to play Diablo 2. When I finished I read Lee's email and tried it again. Now I get no bad RT messages! Now I can go all the way to 64 frames and get no xruns! I cannot do 32 frames because the HDSP cant work that small (If I remember correctly). PD still gets all scratchy when I move or switch windows. Is there some latency in loading modules perhaps, like the lsm module had loaded but not been fully integrated into the scheduler yet? Or could it have something to do with the first way I loaded the module: modprobe realtime gid=500 any=1 (dmesg said groups=any mlock=1) as opposed to the way I have it loaded now: modprobe realtime gid=500 (dmesg says groups=500 mlock=1) ? > > --enable-posix-shm > > Why are you using this option? Because Emmanuel Saracco sent me this url: http://esaracco.free.fr/documentations/linuxaudio/linuxaudio/ Otherwise, I assumed that it already was posix compliant. Isint most of Linux? I guess I am not too sure what POSIX is... In jack do I want --enable-capabilities or not BTW? Please tell me the jack build flags you use. > Otherwise it looks like a PD problem. Do you get any xruns at 256 > frames if you don't connect any clients? As I said PD pops at 256 frames when I move the windows or change windows. I suspect that this is not a PD problem so much as it is a window manager problem. I just built and installed a window manager called fluxbox that is supposed to be pretty light-weight as far as processor usage goes, so I will reboot and see if that does the trick. You see, I dont really have any other sound programs that use jack, but I bet they would do the same thing as PD. Everything else isint time dependant. One last thing: I hear a quiet high pitched noise/hum in the background when I start jackd, and it goes away when I stop jackd. What could this be? Perhaps use of the ramdisk causes my processor to make more electromagnetic noise, that my mixer picks up? Thank you, all of you, for the help! -thewade

Odd. When I run jack from the command line I get none of these error messages, but then again I am not using any verbosity related flags either. > Make sure you are really in group 500 (run "groups" and "grep > 500 /etc/group"). 'id -G' returns 500, and 'cat /etc/group | grep pdman' returns "pdman:x:500:" I seem to recal last time I tried to do the LSM thing I had to patch PAM: could this have anything to do with it? I have selinux disabled also. > Check "dmesg | grep -i realtime" to make sure that > the realtime module is being loaded with the correct options. Realtime LSM initialized (all groups, mlock=1) > Also try > unloading realtime LSM and forcibly reloading it from the command line: > > # rmmod realtime > # modprobe realtime gid=500 done. Now 'dmesg | grep -i realtime' says "Realtime LSM initialized (group 500, mlock=1)" No better performance though. Thanks for the help! -thewade

[linux-audio-user] cross fade loopm which tool

by Atte André Jensen

Hi I recently discovered specimen, and what a nice piece of software!!! But I have a few problematic samples that just won't loop without clicking. I realize that since specimen merely points to samples and only offer basic loop point editing, I should look elsewhere for cross fade loops. But where? Is there a good linux based looping application that I can use for modifying the samples? And (pardon my ignorence) will loop points be saved together with the sample data itself in any format, perferrably one that's read by specimen, or do I have to write down the loop points and set them manually in specimen? -- peace, love & harmony Atte http://www.atte.dk

[linux-audio-user] Keyboard loss @ usb audio disconnect

by Christoph Eckert

Hi all, I'd be glad to hear any comments on the following annoying problem. If we could locate and eliminate the reason for this bug, this would be great. I have various USB audio/midi devices: * Midisport 8x8 * Terratec Aureon USB * m-audio Trigger Finger Not always but often when I disconnect them from my machine, I loose my keyboard so I have to restart the machine. During the shutdown, the machine hangs when shutting down hotplug. After the reboot, some hardware is still messed, e.g. no DSL connection can be established. I have to reboot the machine again, then it works. I tried to monitor the messages-log and the xorg-log but I got no valuable information. I see the following misbehaviours: * No keyboard at all * Konsole (the KDE console emulation) cannot be closed. It hangs * The machine hangs at shutdown when trying to stop hotplug. I see a kernel Ooops, and it reports a segfaut. see http://www.christeck.de/files/DSCN1061.JPG for details. A thing that all used devices share is that they do not register properly on the USB bus. Instead of registering as usb audio devices, these register as HID (human input device) or similar on the bus. The question is: * Anyone else having this behaviour? * Does anyone have a clue which software (hotplug, X.org, KDE) causes the keyboard disconnect? * Any hints which other software components can cause this? I'd be very glad if we could find the reason for this behaviour and report it to the responsible project so the devices can be blacklisteted there. Thanks & best regards ce
