Tim.
I need help troubleshooting a recording issue on
a dedicated audio
computer with a single DSP2000 C-Port. I can not record from the
analog inputs of my audio interface. I suspect that it is because the
analog volume tab on the envy24control mixer is missing which means
that I can not raise (or activate) the ADC sliders.
1) Should the analog tab exist for an ICE1712 device (dsp24 with an
ADC&DAC2000)?
2) If yes - can anyone help me troubleshoot why the tab is not there?
3) Can anybody confirm if the DSP2000's channel LEDs should light up?
(They do light up when using the OEM drivers on an XP partition of the
computer)
A lot of solutions to this problem are “on the envy24control analog
tab, make sure the sliders have been moved up". Without that tab, I
can not see if this is a solution to of my recording woes....
Hello!
Can you please try Mudita24, a replacement for Envy24:
http://code.google.com/p/mudita24/
It is already available as a package in some distros.
I've been waiting for a test case like this!
With Envy24, the support of ADC/DACs was kind of hard-wired.
If it didn't recognize the ADC/DAC, well it just didn't show the tab.
So one of my priorities with Mudita24 quickly became supporting
ICE1712 cards with as-yet unknown future ADC/DACs.
In that respect I rewrote the code to ask ALSA for all the important
information about ADC/DACs, instead of hard-wired info.
Give it a try.
I do expect there might be some issues, being an 'unknown' ADC/DAC.
Perhaps some checkboxes missing etc. ... ?
Let us know.
You can post here or always reach me at
termtech AT rogers DOT com.
Thanks.
Tim.
