Re: [linux-audio-user] newbie question about a Delta 1010LT card

by Joe Dell'Orfano

This may be off your subject a bit, but I can confirm that multichannel recording works with the Delta 1010LT card with Ardour. If you run Jack, by the way, the jack patch bay will show all 10 inputs and outputs on the 1010. Again, this is probably not exactly what you want, but I thought I'd chime in! -Joe -- Joe Dell'Orfano <fullgo(a)dellorfano.net>

[linux-audio-user] Manuals wanted

by Juhana Sadeharju

Hello. I would like to have a look at full set of PDF manuals for the following software. They comes for my personal use only as I'm collecting manuals of audio and graphics software and as I'm helping to make free, open source software better. Cakewalk / Sonar 1.0 Emagic / Logic Audio Platinum 6.0 + effect plugins docs Steinberg / Nuendo 2.0 I have already asked Emagic for their manual but the manuals were available for the product owners, which is sad if somebody like me wants document the audio and graphics software history. Best regards, Juhana

[linux-audio-user] mapping alsa devices to oss devices

by Akos Maroy

In my quest to record from the different channels of the Delta 1010LT have come so far that I can address the different hardware inputs using ALSA device names, while using an appropriate /etc/asound.conf file. e.g. I can arecord -f cd -d 5 -D channel2 test.wav and this would record from hardware input channel #2. I have four stereo input channels, e.g channel1 ... channel4, plus the spdif channel. So far, so good. Now I would need a way to map these channels to OSS /dev/dsp interfaces. something like: /dev/dsp1 -> channel1 /dev/dsp2 -> channel2 /dev/dsp3 -> channel3 /dev/dsp4 -> channel4 I understand that I would need to use the kernel module snd-pcm-oss to achieve this. how can I tell this module to map to the appropriate ALSA devices? BTW, the contents of this asound.conf file is: pcm.ice1712 { type hw card 0 device 0 } # adcdac 1&2 pcm.channel1 { type plug ttable.0.0 1 ttable.1.1 1 slave.pcm ice1712 } # adcdac 3&4 pcm.channel2 { type plug ttable.0.2 1 ttable.1.3 1 slave.pcm ice1712 } #adcdac 5&6 pcm.channel3 { type plug ttable.0.4 1 ttable.1.5 1 slave.pcm ice1712 } # adcdac 7&8 pcm.channel4 { type plug ttable.0.6 1 ttable.1.7 1 slave.pcm ice1712 } #SPDIF channels only pcm.ice1712_spdif { type plug ttable.0.8 1 ttable.1.9 1 slave.pcm ice1712 }

[linux-audio-user] asoundrc for delta 66

by rob

Hi, Can someone show me an example asoundrc for the delta 66 I can't get mine working (everything works fine using oss emulation so I'm pretty sure this is were the problem lies at the moment mine looks like this. pcm.via { type hw card 0 } ctl.via { type hw card 0 } pcm.ice1712 { type hw card 1 } ctl.ice1712 { type hw card 1 } And if I try using it with aplay -D ice1712 it complains thusly: aplay: set_params:805: Sample format non available -- rob <mailingLists(a)pangolin.org.uk>

[linux-audio-user] recording problem with arecord / asound.conf issue?

by Akos Maroy

I'm still playing around and trying to get my Delta 1010LT to work, so I can record from the different input channels. I'm now simply trying to record using arecord, but I can't seem to record anything but silence. the specific problems I get: - I can't recrod from the hardware device as configured /etc/asound.conf I try: $ arecord -f cd -d 5 -D hw test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo arecord: set_params:805: Sample format non available or $ arecord -f cd -d 5 -D ice1712 test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo arecord: set_params:805: Sample format non available where $ cat /etc/asound.conf pcm.ice1712 { type hw card 0 } ctl.ice1712 { type hw card 0 } is the config that was hinted at the 1010LT ALSA driver installation page. BTW, $ arecord -l **** List of CAPTURE Hardware Devices **** card 0: 1010LT [M Audio Delta 1010LT], device 0: ICE1712 multi [ICE1712 multi] Subdevices: 1/1 Subdevice #0: subdevice #0 anyways, what does it mean by "Sample format non available", as the sound card supports this format? also, how do I list the available formats? - I can record from the 'default' device, but only silence I can succesfully run: $ arecord -f cd -d 5 -D default test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo but, it only records silence, even though all my channels are _not_ muted, and I have input running in to the sound card at hardware inputs 3 and 4. I can see this from envy24control. I also experimented with default:0,1 ... 0,3 and default:1,0 ... 3,0, but the same occurs. what am I doing wrong? Akos

[linux-audio-user] Testers for beta version of meterbridge wanted

by Steve Harris

this is not an offical release http://plugin.org.uk/meterbridge/meterbridge-0.9.2.tar.gz The release cycle has slowed down a lot, so I wanted to make sure there aren't any subtle regressions before announcing it. I've fixed a couple of major bugs, and reduced the CPU cost slightly, but there are no new features. - Steve

Re: [linux-audio-user] Laptop/Ozone usb keyboard

by Clemens Ladisch

The "Device Firmware Upgrade Specification" describes a vendor- and device-independent way of downloading a firmware image to a USB device. Older USB devices from Midiman (MidiSport interfaces, KeyStation keyboards) required a device-specific firmware loader, but when a device implements the DFU specification (such as the Sonica or the Ozone), it is possible to use one loader for all these devices, so user's don't have to wait until somebody manages to write a loader for their device. (Of course, now you have to wait for somebody to write the DFU loader, but that's only once. :) Regards, Clemens

[linux-audio-user] command-line recording software?

by Tim

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I want to record audio from my USB port and seek a command line or reliable and simple GUI app. Can anyone suggest what might suit me? I have Edirol UA-1A USB interface which is seen as /dev/dsp1. I intend to record 80 minutes of stereo music on my laptop. The laptop suffers overheating so I need something which uses minimal CPU activity. Otherwise I'd be using Audacity. I'm unable to even compile this software due to the overheating. Debian 3.0r0/Linux 2.4.18 TIA, Tim -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQE+2nYSsUUdIDHrdAURAuA1AJ92JjXQ3EE7wESOv6SRgfgcF5yppwCgoLEh exSzf48csmGri6QMoerd9Sw= =MEy8 -----END PGP SIGNATURE-----
