I took a look at the agnula.org page thinking I'd get a copy of the upgrade CDs for my existing Debian system. Downloading two CDs worth of data on an ISDN connection is going to take too long... does anyone in the UK have the DeMuDi 1.0 add-on distribution that they'd be prepared to copy and snail mail to me for a fiver or whatever it costs? Or have I missed somewhere on the web site that says CDs can be obtained by snail mail? -- Anahata anahata(a)treewind.co.uk Tel: 01638 720444 http://www.treewind.co.uk Mob: 07976 263827

[linux-audio-user] bad sound quality (under a non-libre OS good)

by Miernik

I am installin Debian GNU/Linux on a Sony PCG-C1MV notebook computer. The owner of this computer is very picky aboud audio quality. I cannot make it work so the sound quality would be as good as in some non-libre operating system, which Sony has installed on it. I am playing exactly the same sound wav file, and under Debian GNU/Linux the audio quality is much worst than under the non-libre OS. The sound card is a PCI card like this: 00:06.0 Multimedia audio controller: ALi Corporation M5451 PCI AC-Link Controller Audio Device (rev 02) Subsystem: Sony Corporation: Unknown device 80ec Flags: bus master, medium devsel, latency 64, IRQ 9 I/O ports at 1800 [size=256] Memory at e8100000 (32-bit, non-prefetchable) [size=4K] Capabilities: [dc] Power Management version 2 I am using ALSA with the snd_ali5451 driver, but I also tried Knoppix and Gnoppix, (which autodetects and installs the trident OSS driver) and the problem is more or less the same, maybe a little better, but maybe not, hard to tell. I must say that for me the difference is very tiny, and I would not even notice that something is wrong, and I can only notice that there is a difference if I play on one OS and the immidiately reboot to Debian and listen to the same file. Otherwise I simply forget that it should be any better. The bad quality doesn't look like any extra noise, it looks more like some kind of distortion. It doesn't depend on video usage, moving windows, etc. Just in case, the video card is: 00:0c.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY (prog-if 00 [VGA]) Subsystem: Sony Corporation: Unknown device 80ec Flags: stepping, medium devsel, IRQ 9 Memory at f0000000 (32-bit, prefetchable) [size=128M] I/O ports at 2800 [size=256] Memory at e8110000 (32-bit, non-prefetchable) [size=64K] Expansion ROM at <unassigned> [disabled] [size=128K] Capabilities: [50] Power Management version 2 The card doesn't use DMA: venezia:~# cat /proc/dma 4: cascade venezia:~# The same under Knoppix. Also while playing a sound file. I've read the Audio-Quality-HOWTO for Linux at http://www.linuxdj.com/audio/quality/ but it didn't help. I've tried booting with the no-hlt option, no difference. I use the 2.6.0-2 kernel from Debian. What to do to make the audio quality as good as in the non-libre OS? -- Miernik ________________________ jabber:miernik@amessage.info ___________________/__ tel: +48608233394 __/ mailto:miernik@ctnet.pl Learn about crime done by George W.

[linux-audio-user] [ANN] AlsaModularSynth-1.7.2

by Matthias Nagorni

Hello, after I noticed that polyphony was completely broken in ams < 1.7.2 I rapidly fixed it (thanks to Fons Adriaensen for valueable hints). Some of the patches used for the sound examples published by german Keyboards magazine are now available for download as well. You might also enjoy the new phaser instrument patch and its "Haunted Castle"... Have fun !

[linux-audio-user] [ANN] TimeMachine 0.2.1

by Steve Harris

http://plugin.org.uk/timemachine/ * Now uses GTK, instead of SDL to draw the window, hopefully a bit more friendly on maintainers. * Meters. * Now records up to 8 channels (use the -c flag). * Can set the output directory/file prefix (-p flag). * Hiting the window close icon now makes sure you have all the data written to disk. I've a feeling that someone mailed me a patch and I've lost it and not included it, so if its you please mail me again. Enjoy, Steve

Re: [linux-audio-user] Motherboard recommendation?

by davidrclark＠earthlink.net

Joe, I just built a new machine a week ago, so I'm somewhat current on what's out there. My first question is: Why 2.4 GHz? Is this an old processor that you're putting into a new mobo? For music, especially for real-time, you need balanced speed (speed everywhere). As far as I could determine, the 2.4 GHz processor has a 400/533 MHz FSB whereas the 2.6 GHz processor has 400/533/800. The 800 MHz FSB requires two sticks of memory (inserted properly), but it would be significantly faster than what you are considering, not because of the 0.2 Hz clock speed increase, but due to the FSB speed. The 2.6 GHz processor can also use the 865PE or 875P chipset-based mobo's to full advantage. If you can do it, I would highly recommend that you reconsider choice of processor if at all possible (and assuming that you're serious about music apps --- or gaming or anything that requires speed). The reason I mention this is that you brought up dual-CPU mobo's. You can almost get that performance increase compared to what you are asking about by reconsidering the processor and memory. If you need to stick with the processor, then I'll have to let someone else help out, not being familiar with other combinations. Good luck! Dave.

[linux-audio-user] RME Hammerfall setup difficulty

by linux-audio-user＠k--b.org

Hello all. I have recently installed Debian and compiled 2.6.0-9test for a new Hammerfall digi9652 card I purchased. I'm having a very difficult time getting alsa to recognize the card and am hoping someone here might have some ideas. The most damning symptom is that cat /proc/asound/cards gives only: ---no soundcards--- Running aplay phone.wav (as root and reg users) gives the following error: aplay: main:484: audio open error: No such device And trying to start alsamixer (as root and reg user) gives: alsamixer: function snd_ctl_open failed for default: No such device I have heard that some professional soundcards do not have hardware mixers. The user's manual for the Hammerfall digi9652 doesn't say anything about a hardware mixer so this could be the case for this card. I have pasted background information below that I hope might be helpful. Thank you in advance for any advice you might provide. Kris Bergstrom Los Angeles, CA SYSTEM uname -r 2.6.0-test9 I checked all the dependencies of the kernel before compiling and they were fine. I compiled the kernel without error. soundcard: RME Hammerfall digi9652 ALSA RELATED dpkg -l | grep alsa ii alsa-base 0.9.6-5 ALSA sound driver common files ii alsa-utils 0.9.6-1 Advanced Linux Sound Architecture (utils) ii alsaconf 0.9.6-5 ALSA configuration generato more /etc/modprobe.d/alsa ### DEBCONF MAGIC # This file was automatically generated by alsa-base's debconf stuff alias char-major-116 snd alias char-major-14 soundcore options snd major=116 cards_limit=4 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 alias snd-card-0 snd-rme9652 alias snd-slot-0 snd-card-0 alias sound-slot-0 snd-slot-0 lsmod: Module Size Used by snd_seq_oss 34048 0 snd_seq_midi_event 7936 1 snd_seq_oss snd_seq 54160 4 snd_seq_oss,snd_seq_midi_event snd_seq_device 8200 2 snd_seq_oss,snd_seq snd_pcm_oss 51876 0 snd_mixer_oss 18944 1 snd_pcm_oss snd_rme9652 27972 0 snd_pcm 96292 2 snd_pcm_oss,snd_rme9652 snd_page_alloc 11780 2 snd_rme9652,snd_pcm snd_timer 25220 2 snd_seq,snd_pcm snd 48996 9 snd_seq_oss,snd_seq_midi_event,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_rme9652,snd_pcm,snd_timer soundcore 9152 1 snd 8139too 20736 0 mii 5248 1 8139too crc32 4608 1 8139too af_packet 16904 2 In case it's of use: I accidentally ran ./snddevices when trying to debug the problem.

If that were causing problems, I'd assume it would be a problem of only being able to run a program as root but I could certainly be wrong. -- H5n9d0+5

[linux-audio-user] [OT?] Fun with numbers

by Dave Phillips

Greetings: I thought about posting a response to the linuxaudio.org controversy but I've opted for posting some numbers instead. It was pointed out that LAD can claim more than 700 members now. Very cool, I love it. I'm not sure exactly what those numbers mean, but I do know that only about 1/10 of that figure actually post regularly to the list. So out of the 700 only ~70 are consistent contributors. Again, I don't know what the numbers signify. I guess it's [your meaning here]. On January 7 Linux Journal On-line posted my second monthly column (this one about Planet CCRMA and AGNULA). I checked for the number of reads this morning: +10000. That's right, more than ten thousand in little over one week. I point this out not to shine my own light, but to indicate again that far more people are interested in Linux audio development than the mail lists' membership numbers suggest. (Actually I have a lot of thoughts on all this stuff, but I'm really just too busy here for further comment.) Back to the hack... Best regards, Dave Phillips

[linux-audio-user] Motherboard recommendation?

by Joe Button

Hi. Can anyone recommend a motherboard for Linux / multimedia? Probably mostly Ardour and + some softsynths. I have a P4 2.4Gb / Socket 478 I'd like to put in it. As an aside, are dual mobos considered a good idea for realtime stuff these days? Just asking out of interest, don't think I'm going to get one this time around. Cheers.
