Hi all,
I have a problem setting up my AD hardware with
Linrad.
My system is a Mandrake 9.1 with two “audio”
boards.
Both audio boards have been tested and work with
programs like SOX, and the system audio mixer.
All the installation process was perfect: svgalib,
nasm, Linrad 01-17. Everything OK.
My first audio board is a Sound Blaster compatible
card. In the U option, Linrad detects it under /dev/sound/dsp and can be
configured without any problem.
The second audio board is a Bt878a TV card. It can
be used as ADC up to 448000 samples per second and 16 bits. I know this can be a
bit strange but you can read the setup process here: http://www.domenech.org/bt878a-adc/index-e.htm
In the U option Linrad says:
=cut=====================================
Checking device drivers 00:/dev/sound/dsp 44100 Hz 2 Chan. 16 bit 02:/dev/sound/dsp1 32000 Hz 2 Chan 16 bit 03:/dev/sound/dsp2 448000 Hz 2 Chan 16 bit Select device for input by line number _ =cut=====================================
If I select “00” it works but if I select “03” (the
Bt878 ADC) it says “ERROR (press any key)”. Doesn’t matter if I try “03”,“3”,
“02”, “2”, always the same message.
I know this is not a standard sound device and
maybe has not much sense to worry about, but I think it’s a pity to get so close
(Linux and Linrad detects the hardware) and loose the opportunity to play with
higher frequencies with low cost hardware.
At the bottom you have my
“soundboard_init.log”.
thanks!
