[linux-audio-user] [ANN] ams-1.5.5 fixes serious bug

by Dr. Matthias Nagorni

Hi, ams-1.5.5 is available from http://www.suse.de/~mana/kalsatools.html. It fixes a serious bug in synth.cpp which causes the machine to freeze when ams is started as root. Some example patches for the bode frequencer LADSPA plugin included in the new 0.3.3 version of Steve's plugin set have been added as well. Have fun !

[linux-audio-user] mp3 live-encoding with sox and lame

by Christoph Rupp

Hello list! (I have searched for an answer to this question in google and some other lists but didn't find something helpful... sorry if this has been asked before) i want to have realtime-encoding of my soundcard line-in with sox and lame (or something similar - i need command line tools). Now i use rec -t wav -r 44100 - | lame -m m -a -b 64 - (i need 44.1 khz/64 kbit). But all 5 or 7 hours sox crashes; there's an older thread on the sox mailing list: http://sourceforge.net/mailarchive/forum.php?thread_id=1083489&forum_id=3958 which says that this is due to a counter in the wav header which overflows and that you should use .raw instead of .wav. But whatever i use doesn't sound right: sox -t ossdsp -w -s /dev/dsp -t raw -r 44100 -c 2 - | lame -r -m j -b 64 -x -s 44.1 --resample 44.1 - It sounds dump: http://www.kochenmachtspass.de/test3-ms.mp3 I have tried many other options like -c 1 (leads to noise) but i cannot find a solution... Maybe someone of you knows a solution? Thanks Chris ===== http://www.crupp.de __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

We will recheck. I have immense faith in Fernando, but everyone makes mistakes.

[linux-audio-user] SMP motherboards?

by Taybin Rutkin

Does anyone have any recommendations for cheap SMP motherboards? Something that can handle a couple 667 PIIIs would be ideal, but if the total price including CPUs is <$300, I'll consider it. My motherboard seems to not work with SMP anymore (freezing, restarting). I'm pretty sure it isn't a kernel thing because I've tried every version between 2.4.17 and 2.4.20 and they all act the same. It used to be rock solid at 2.4.18. Alternatively, I'd like the name of a good vendor of motherboards. Taybin -- http://www.piratesvsninjas.com

by Mark Knecht

Thanks Paul. I'm still struggling with getting this new card going. Fernanado and I are working through the issues one at a time by doing a Planet RPM for the newest version alsa and have applied the one line patch that you pointed me at the other day. However, I'm still not running. 1) Fernando applied the one line patch applied: --- hdsp.c-orig 2002-12-03 19:28:40.000000000 +0000 +++ hdsp.c 2002-12-03 19:28:06.000000000 +0000 @@ -2966,6 +2966,7 @@ switch (rev & 0xff) { case 0xa: + case 0x64: /* hdsp_initialize_firmware() will reset this */ hdsp->card_name = "RME Hammerfall DSP"; break; 2) Alsaconf works, sort of. modules.conf gets built, but my machine will not reboot after running it. Don't know why. 3) When I boot I see the following message in /var/log/messages Dec 9 12:39:40 Godzilla kernel: Hammerfall memory allocator: buffers allocated for 1 cards Dec 9 12:39:40 Godzilla kernel: RME Hammerfall-DSP: no cards found Dec 9 12:39:40 Godzilla insmod: /lib/modules/2.4.19-1.ll/kernel/drivers/sound/pci/rme9652/snd-hdsp.o: init_module: No such device 4) lspci -v shows the card is there: 00:0f.0 Multimedia audio controller: Xilinx, Inc.: Unknown device 3fc5 (rev 64) Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at f6000000 (32-bit, non-prefetchable) [size=64K] I'm completely puzzled.

[linux-audio-user] PCI_DEVICE_ID_XILINX_HAMMERFALL_DSP

by Mark Knecht

Hi, Where are the definitions for PCI_DEVICE_ID_XILINX_HAMMERFALL_DSP and PCI_VENDOR_ID_XILINX kept in the alsa code? Thanks, Mark static struct pci_device_id snd_hdsp_ids[] __devinitdata = { { .vendor = PCI_VENDOR_ID_XILINX, .device = PCI_DEVICE_ID_XILINX_HAMMERFALL_DSP, .subvendor = PCI_ANY_ID, .subdevice = PCI_ANY_ID, }, /* RME Hammerfall-DSP */ { 0, }, };

[linux-audio-user] [pw_lists@slinkp.com: snd-usb-audio and Midiman Oxygen]

sorry for the crosspost, but i'm not getting any response from alsa-user list and I know these devices have been discussed here before.

I'm (relatively) new to Linux, so I've come to the conclusion that I need to put seqencing and more compicated things like that in the future. Having ecasound (on my main computor) and my (now finished) dedicated RTSynth box together I can do it like they did in "the old days" while I slowly try out (and learn) more advanced things now that I finally upgraded from SuSE 6.4 to SuSE 8.1. That upgrade was like opening up pandora's box. > ditto for the introductory material for terminatorX, Mix, Ceres, > Cecilia, and some others. They happen to be programs I haven't tried. So those chapters will introduce me to those programs. > The book is very weak with regard > to technical aspects of ALSA, nor does it offer much to the > would-be developer. I hope to change that aspect in v. 2.0. Perfect! Being that I've been using SuSE 6.4 (up to the upgrade) I haven't even approached alsa yet. And I don't want to until I *have the time and attention* it deserves. I'll read the other chapters and get aquainted with what has come before (again... I'm still kind of a newbie). Meanwhile oss is allowing me to get things done. You've given me an outline of what to look for (in your book) and what to keep in mind as being (possibly) out of date. I will focus on those chapters. Maybe by time I'm ready to focus on the more newer developments, the new book will be out. > I suppose a lot of the material is most useful as starting points, As a (seasoned) newbie, I'm sure it will help. I've jumped right in the middle of all this and need some starting points. I'm in this for the long haul, so I don't mind getting the background on the fundimentals.

I'm not familiar with the -z:nointbuf but I've had exactly the same noise as you described and I was able to get rid of it with the -b option. It was tricky though. I stared with -b:64 (didn't work), then I doubled to -b:128 (didn't work). To make a long story short, after doubling for a while, I ended up dropping the number by 100, then by 50... until I narrowed it down to the _exact_ buffer size that stopped the clicking. It may be different for you, but I think the number that worked for me (at the time) was -b:150. BTW, they say that the -b option works best with even numbers.

Yea... if you're putting a "line level" device (sometimes marked as "aux") into a mic input, you are sending a higher voltage level into than the mic input is designed to take. I think you could actually damage something (possibly). Rocco __________________________________________________________________ The NEW Netscape 7.0 browser is now available.
