I see. Anyway, if anybody could tell me how to build it up... just to try... Maybe one day I'll find a more powerful pc... :-) L.

[linux-audio-user] Terratec PHASE 28

by Petar Nedyalkov

Hello list, I've successfully installed ALSA on my server, having two Terratec PHASE 28 cards. The problem is that from all 8 sound outs, the mixer recognises as stereo pairs only four. The `amixer -c 0` output is as follows: Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 255 Front Left: Playback 255 [100%] [on] Front Right: Playback 255 [100%] [on] Simple mixer control 'PCM',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 128 Mono: Playback 128 [100%] [on] Simple mixer control 'Front',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 127 Front Left: Playback 127 [100%] [on] Front Right: Playback 127 [100%] [on] Simple mixer control 'Center',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 127 Mono: Playback 127 [100%] [on] Simple mixer control 'LFE',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined Playback channels: Mono Limits: Playback 0 - 127 Mono: Playback 127 [100%] [on] Simple mixer control 'Side',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 127 Front Left: Playback 127 [100%] [on] Front Right: Playback 127 [100%] [on] As you can see, the mixer controls Side and Front are stereo (i.e. have two channels), but the mixer controls Center and LFE are mono. The same goes to my second Terratec PHASE 28 card. Unfortunately, I had installed the same versions of ALSA and the channels were OK. But after I reinstalled my server - the Center and LFE stereo channels became mono. I'm using ALSA drivers 1.0.9, ALSA utils 1.0.9 and ALSA lib 1.0.9. Has anyone solved this problem? I need 4 stereo channels but not 2 stereo and 2 mono. -- Cyberly yours, Petar Nedyalkov Devoted Orbitel Fan :-) PGP ID: 7AE45436 PGP Public Key: http://bu.orbitel.bg/pgp/bu.asc PGP Fingerprint: 7923 8D52 B145 02E8 6F63 8BDA 2D3F 7C0B 7AE4 5436

[linux-audio-user] Boot Demudi Live from hd

by Jody

Hi, I'm testing Demudi Live v 1.2.1, hope the response is not hidden by my nose, I'd like to run the live-system from hard drive instead of runing from CD-Rom. I use parameter fromhd=/dev/my_partition or bootfrom=my_iso_image.iso with KNOPPIX to speed up access, is there a similar cheatcode for this Demudi Live version ? With many thanks, Jody

[linux-audio-user] Ardour and Linux

by Favio＠gmx.net

Hi there, could someone help me to get started with Linux on my Laptop? I want to have a look at Ardour and if you could point me to an OS and how to install what, then that'd help me a lot. I have an older system CPU 1.2 GHz and 90something RAM, also my soundcard works with Asio drivers and USB. If you could help me with this, I'd be very grateful, Cheers, Favio -- Favio Masulli y Becker Contact: 07840 185 746 MSN : protoolz(a)hotmail.co.uk

[linux-audio-user] New track, old tracks updated

by Stuart Allie

Hi All, New music at http://allie.opensrc.org Finally got a new track to put up. "Haunted Hope" is the piece I am most happy with to date. It is a bit different to to my previous work - more melodic, more interesting harmonically and rythmically. (I think so anyway). It was also composed and mixed differently, using muse and ardour for the first time. Because of instabilities with ardour on my machine, the final mix ended up being done with ecasound. (I've got a mostly-working python script to read the ardour file and produce an almost-equivalent ecasound ecs file.) Midi files: I've uploaded midi files for each of the 4 pieces on my site - they are in the midi_files directory. Please feel free to download the midi files and use them in whatever way you like. I'd be *really* interested in hearing other people's renderings of the pieces. MP3 files: I've added mp3 versions of each track for those that prefer that format. They are available in the mp3 directory. New Mixes: Updated mixes of the first 3 pieces, "Can't Beat Them", "Takes Two", and "Feeling Slow". The changes include: * More interesting drum and bass lines. * Better drum sounds (Natural Studio nskit7). * Better mixing and mastering after doing some actual reading on the subject. * New synth sounds - using ams and zynaddsubfx now. Both are fantastic softsynths. If you heard these pieces before I'd love to hear your comments on the new mixes. Also, on my wiki page at musicians.opensrc.org I've put a list of gear I am thinking of buying over the next year or so. I'd welcome any comments people have on quality/value-for-money/suitability etc. Cheers, Stuart

Hi folks, I'm an absolute newbie to Linux. I installed the latest "musix" distro in the Knoppix mode and I've got a Gina24 that is not recognized by the alsaconfig tool. What do I have to do to get it running? Thanx a lot in advance! All the best, FRitz

[linux-audio-user] terrible sineshaper dependencies

by Nigel Henry

Hi. Has anyone got sineshaper installed on FC3? I'm having the most terrible dependency problems. gtkmm, then glibmm, and the list of deps goes on and on. I thought that Fedora extras handled thes deps, but adding the urls to yum for the fedora extras hasn't solved it. Yum says gtkmm doesn't exist. I'm not knocking anything. I'd just like to get sineshaper working, as it sounds like a good synth. Any tips, hints. Nigel.

[linux-audio-user] verdict on edirol fw products

by Noah Roberts

I am looking to purchase a nice soundcard for the laptop. What is the verdict on the Edirol Firewire stuff? How about the USB2 stuff? I'm especially interested in products like the FA101 or UA101. Will this type of soundcard have better physical latency than my integrated POS? Also interested in any other ideas.

[linux-audio-user] APIC, IRQ, and an HDSP9652

by Nathan

Hi all, This is my first post here, so hello everybody. I'm running PlanetCCRMA's FC3 distro (low-latency kernel 2.6.11-0.3.rdt.rhfc3.ccrma) on an Athlon 64 3000+ w. an NF4 chipset. As far as sound goes, I'm using the integrated CK804 (w. snd-intel8x0 drivers) and an RME HDSP9652 (w. snd-hdsp). The questions: 1. I've read a lot about getting the IRQ of the soundcard to as high a priority as possible. How important is this? Is it possible with setpci if I reserve an IRQ in the BIOS, or only by swapping cards? 2. Should I enable or disable APIC? I've heard muddy answers, but what I know is that it always leaves my HDSP9652 at IRQ's from 16-20. Here's the output of cat /proc/interrupts. # cat /proc/interrupts CPU0 0: 1556590 XT-PIC timer 0/56590 1: 3324 XT-PIC i8042 0/3324 2: 0 XT-PIC cascade 0/0 3: 3948 XT-PIC NVidia CK804 0/3948 4: 0 XT-PIC hdsp 0/0 5: 97413 XT-PIC ohci_hcd, nvidia 0/97413 7: 0 XT-PIC parport0 0/0 8: 1 XT-PIC rtc 0/1 9: 0 XT-PIC acpi 0/0 10: 0 XT-PIC libata, ehci_hcd 0/0 11: 37516 XT-PIC libata, eth0 0/37516 12: 146561 XT-PIC i8042 0/46561 14: 15416 XT-PIC ide0 0/15416 15: 12105 XT-PIC ide1 0/12105 NMI: 0 LOC: 1556573 ERR: 0 MIS: 0 3. Would you recommend I set my first soundcard to be the CK804 or should I leave the RME as the first soundcard? 4. Should I just disable the CK804 and throw in an emu10k1? Becuase I could do that, too. Any help would be appreciated, and if I left something out, let me know. Thanks! -Nathan
