Dear all,
This is a newbe question. I've almost no knowledge in sound handling
and can't get further without some hints.
I've shortly acquired a Terratec iVinyl PhonoPreAmp. It's USB and
works under os-x or window$ without requiring any particular device
driver for recording. An included proprietary software is required for
32 bits recording (which is not in my plans)
Ubuntu 7.10 'gusty gibbon' hotplugs an usb1 audio device and set alsa
with snd-hwdep, snd-usb-audio and snd-usb-lib for hw:1,0 accordingly.
Alsamixer shows for the iVinyl device a simple 'mic' switch as a
unique controler (no volume or other tuning at all). This seams to be
also the case on the other plateforms.
Here the output of `cat /proc/asound/cards´
0 [AudioPCI ]: ENS1371 - Ensoniq AudioPCI
Ensoniq AudioPCI ENS1371 at 0xdc00, irq 11
1 [iVinyl ]: USB-Audio - PhonoPreAmp iVinyl
Terratec PhonoPreAmp iVinyl at
usb-0000:00:11.0-1, full speed
Having found working parameters for iVinyl by running `arecord´ with all
available formats, i can now run the following command and get a vinyl recorded:
$ #
$ # Notice:
$ # Format is mandatory. And only `S24_3LE´ seams to be working.
$ # Channels is mandatory.
$ # Rate default to 32000 if unset. 44100, 48000, 96000 may be set.
$ #
$ arecord -v -D iVinyl -f S24_3LE -r 44100 -c2 test.wav

But Audacity crash miserabily as soon as AudioI/O preferences are
saved with recording device set to iVinyl (hw:1,0) and S24_3LE format
doesn't seams to be well accepted by jackd. I've played for hours
around .asoundrc trying to fix this issue.:(
Furthermore, this device doesn't "exist" by Alsa for the moment, isn't
said "works with linux" by it's manufacturer, nor did I found any
usable tips in linux forums or in google...
In other words i'm stuck.
Q1: How may I fix -f, -r and -c options of the `arecord´ command into
a named setup for capture device in the asoundrc file (for example, in
a way that may be directly used by calling 'arecord -D vinyl48
toto.wav' ) ?
Q2: What should be done in order to get Jackd and/or Pulseaudio
working with this device ?
Q3: Are there other alternatives ?
Many thanks in advance for your tips.
Kindest regards
blonchk
