[linux-audio-user] .asoundrc and the sequencer

by rob buse

hello everyone, I'm wondering if its possible to manipulate my sequencer clients using .asoundrc ? I have my laptop with its cs46xx card which always gets installed as sequencer client 64:0. When I plug in my midiman 2x2 it gets registered as clients 72:0 and 72:1. basically, I want to either place the midiman 2x2 as client 64:0 and 64:1 on start up, or somehow use parameters in the modules.conf file to not load the cs46xx's sequencer portion (since my laptop has no midi out). I see there are some sequencer related things in the .asoundrc file, but I really can't find what they do. Any suggestions ? cheers rob _______________________________________________________ Sent through e-mol. E-mail, Anywhere, Anytime. http://www.e-mol.com

[linux-audio-user] Re: Processor Recommendation

[linux-audio-user] Hydrogen users ?

by Dave Phillips

Greetings: I'm troubleshooting some problems with the Hydrogen rhythm composer, and I wondered if anyone else on the list has been using the program. For some reason yet unclear my saved drum kits are completely garbled and crash Hydrogen when I try to load them. Has anyone else built and saved their own drum kits in Hydrogen ?

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

by Akos Maroy

Hi, I just installed a Delta 1010LT multi-channel audio card into my PC. I'm new to multi channel cards, and have some questions. I'm sorry if these questions are dull or simple. I just installed alsa 0.9.4, as described on the page http://www.alsa-project.org/alsa-doc/doc-php/template.php3?company=Midiman&… all modules seem to load fine. I have the following questions: - mixer I can also run alsamixer and env24control, but I can't run aumix or other mixers that would use the OSS mixer interface. maybe the alsa -> OSS mixer interface is not configured properly, as: # cat /proc/asound/card0/oss_mixer VOLUME "" 0 BASS "" 0 TREBLE "" 0 SYNTH "" 0 PCM "" 0 SPEAKER "" 0 LINE "" 0 MIC "" 0 CD "" 0 IMIX "" 0 ALTPCM "" 0 RECLEV "" 0 IGAIN "" 0 OGAIN "" 0 LINE1 "" 0 LINE2 "" 0 LINE3 "" 0 DIGITAL1 "" 0 DIGITAL2 "" 0 DIGITAL3 "" 0 PHONEIN "" 0 PHONEOUT "" 0 VIDEO "" 0 RADIO "" 0 MONITOR "" 0 - accessing the multiple input channels as separate OSS devices actually the main goal of having this card is to be able to record parallelly from the separate input channels it has. recording would be done through opening and reading OSS-style /dev/dsp devices. is this possible using this card and alsa drivers? if so, how? is this related to /etc/asound.conf ? all help would be appreciated, Akos

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
