Recensione di Compatibilità con Linux

The ESI U24 XL from EGO SYStems (product page) is a 24bit converter that is connected via USB and provides the following connections and components:

  • Analog input: the analog input stage uses NJM4850 operational amplifiers. Each channel has its own op-amp.
  • Analog output: the output uses a NJM4556. One op-amp is used for both output channels.
  • USB audio streaming controller TE7022L from Tenor.
  • As DAC and ADC the WM8776 from Wolfson Microelectronics is used.
  • (probably) Suntec transducer for the coaxial SPDIF output

The Printed Circuit Board is identified by the printing “U24 XL Rev1.1″ and has the USB-ID 0a92:00d1:

Testing

The U24 XL was tested in combination with the following hardware (09. April 2013):

  • Lenovo Thinkpad i5 (ivy)
  • Debian Wheezy
  • Kernel 3.2.0-4-amd64 (3.2.41-2)
  • Kernel 3.4.39 (from Kernel.org)

The following inputs and outputs can be selected in KDE (Phonon, VLC backend):

  • Analog stereo duplex
  • Analog stereo output + digital stereo (IEC958) input
  • Analog stereo output
  • Digital stereo (IEC958) output + analog stereo input
  • Digital stereo duplex (IEC958)
  • Digital stereo (IEC958) output
  • Analog stereo input
  • Digital stereo (IEC958) input

alsamixer can control the level of PCM and Capture.

Linux support of the following inputs and outputs was tested and functionality was proven:

  • analog output
  • analog input
  • optischer SPDIF output with CD

Test with Alsacap

ALSACAP was tested on an old notebook with Debian Squeeze:

2.6.32-5-686 #1 SMP Mon Feb 25 01:04:36 UTC 2013 i686 GNU/Linux

(N.B.: libasound-dev had to be installed to successfully compile alsacap.)

      Subdevice 0, name `subdevice #0'

However, ALSACAP does not compile without errors on Debian Wheezy:

install -D -m 755 alsacap /usr/local/bin/alsacap
install -D -m 644 alsacap.1 /usr/local/share/man/man1/alsacap.1
install: cannot create directory /usr/local/share/man/man1: No such file or directory
make: *** [install] Error 1

****  Installation failed. Aborting package creation.

Some changes are necessare in the “Makefile”:
The directory /usr/local/bin/ is correct.
But the path for the manual is wrong:
The path /usr/local/share/man already exists, but the sub-folder “man1″ is missing. After removing this sub-folder from the Makefilde, checkinstall runs successfully.

(N.B. and warning: If the package alsacap is deinstalled, the whole folders will also be removed).

The program creates the following files:

/usr/local/bin/alsacap
/usr/local/share/man/alsacap.1
/usr/share/doc/alsacap/LICENSE

(N.B.: It is preferred to remove the files manually for deinstallation, bypassing DPKG)
