Re: [linux-audio-user] Sounds Expo in the UK

by Daniel James

Hello all, Please forward this to all relevant lists. I've negotiated with the organisers of Sounds Expo 2004 (a studio technology trade show taking place near London, England, 10th to 12th February) to have a Linux audio and music stand. http://www.sounds-expo.co.uk/index2.php This will be a non-commercial stand demonstrating Linux audio systems and offering free advice from Linux experts. What we need now are: 1. Firm commitments from people who can travel to London on these dates and offer help on the stand (doesn't have to be all three days). You need not be an expert, as you won't be on the stand on your own - a Linux audio user who is confident to talk about their experience would be great. If you can bring hardware that would be a bonus. 2. Offers of sponsorship for the stand - we will need to cover venue expenses, as we can't expect the organisers of the event to subsidise the stand. I believe this is the first time that an event of this type will have a Linux stand, and I think it's really important to get the software in front of a specialist audio (but non-Linux) audience. Cheers Daniel

I have successfully captured and sent 2 channel audio from both dev 0 and 1, but I (as I am VERY new to ALSA and the .asoundrc voodoo) have not been able to use all 8 channels of ADAT optical io. The goal of my setup is to capture 8 streams into Ardour via jackd from the ADAT in but I have yet to figure out how to access all of the interleaved data. Please excuse me if my difficulty is naive but as I said I am new to the finer workings of alsa and am eager to get some direction beyond the fragments found in news group archives. Sincerely, James

[linux-audio-user] jack-configuration

by Julien Claassen

Hi everyone! Do you know, if there is a pendant to the .asoundrc in jack. Can you write a .jackrc to declare named inputs/outputs with a specified number of channels? If this is possible, how? I.e. let's say I wanna combine my third and fourth channel on the soundcard (delta 1010lt ice1712) to one jack-input. Thanks for any help!

Re: [linux-audio-user] How to record PCM signal?

by Eduardo Guerrero

I'm sorry, seems like my reply button only sends to the author and not to the list. Here's my reply: > hardware playback port. You can use the monitor ports as input > to qarecord to capture everything you hear from your playback > ports. > > I checked the monitor box in the options and I got 2 more outputs in qjackctl connection panel, however I can't find how to connect qarecord, it doesn't show anywhere and the meters don't move when I play. Maybe a command line option has to be enabled. I'm starting it with just qarecord & Thanks, Eduardo.

[linux-audio-user] How to record PCM signal?

by Eduardo Guerrero

Hi, I'm trying to record what I play with Zynaddsubfx and Hydrogen in a stereo wav file but haven't got results so far using Audacity and QARecord. My card is a sblive and for everything it works fine. I've been testing different settings on the connection panel in qjackctl but still nothing. It seems like I'm not routing the audio as it should go. Any pointers? Thanks, Eduardo.

[linux-audio-user] ALSA -> OSS DSP question

by Akos Maroy

Hi, I posted on this list a while ago, but still couldn't resolve one of my problems. I have a Dela 1010LT card, which works nice with the envy24 ALSA driver. What I want to achieve is to record from this soundcard through the OSS interface. I've been experimenting with /etc/asound.conf and the aoss utility, but to no avail. Basically what I want to achieve is to have a two channel /dev/dsp device, which corresponds to adc 3&4 on the Delta card. in /etc/asound.conf I have: # adcdac 3&4 pcm.channel2 { type plug ttable.0.2 1 ttable.0.3 1 slave.pcm ice1712 } which works nice when I use arecord -D channel2 ... now, what I want to work is something following: aoss sox -t ossdsp -r 44100 -c 2 -w /dev/dsp0 -t wav tmp.wav but no matter how I try to generate a pcm.dsp0 section in /etc/asound.conf, what I record is total silence :( as far as I understand, I need a pcm.dsp0 section, which would describe the /dev/dsp0 features. what I tried, among others is: pcm.dsp0 { type plug slave.pcm "channel2" } but this doesn't work. (it may be a problem that there is actually an OSS-driven /dev/dsp0 in the system. but setting pcm.dsp1 didn't work, it gave me non-existent device errors) can someone give me hints on setting up a proper pcm.dsp0 section?
