I was able to successfully install the DTRC in a WinXP bottle on the following machine:
Soyo SY-7ISA+ Intel i815 Motherboard
Intel Pentium III 866 MHz Processor
512 MB SDRAM
PNY Verto GeForce FX 5200 AGP 8x 256 MB DDR
Creative Labs Sound Blaster Live! 5.1 PCI Sound Card (SB0220)
Samsung CD-RW/DVD Drive Model: TS-H492A/RSWN
Dual Boot openSUSE Linux 10.3/Windows XP Pro SP3
CodeWeavers CrossOver Games for Linux Version 7.1.2
Installation is a little awkward since the application is provided in a .ZIP file with no installer. I unzipped the archive into a temporary directory and executed the DTRC.exe file just to have something run during the CrossOver installation process. While DTRC.exe was running during new software installation, I copied the temporary directory containing the application into the Program Files directory of the new bottle. I then closed DTRC, and waited for the installation process to terminate normally. I then selected the option to Run a Windows Command and created a desktop shortcut to the DTRC.exe file in the new application directory within the Program Files directory in the bottle.
DTRC runs correctly on my system provided the correct mixer settings are selected. The dashed vertical bars noting the Mark and Space frequencies are present in the spectrum display as are the frequency and offset values. The XYScope displays the elliptical representations for Mark and Space. The signal strength indicator functions properly. Incoming data is transmitted to the UTARC server correctly.
I use KDE and KMix as the mixer. Since the mixer settings seem to be crucial to getting the application to work properly, here are my settings provided I have audio input from the receiver connected to the Line Input jack of the sound card:
INPUT
Bass: Selected (Red), 50% position
Treble: Selected (Red), 50% position
3D Control Sigmatel Depth: Selected (Red), Maximum position
3D Control Sigmatel Rear Depth: Selected (Red), Maximum position
Front: Not Selected (Red)
Surround: Not Selected (Red)
Synth: Not Selected (Red)
Wave: Not Selected (Red)
Line: Not Selected (Red), Selected (Green)
Line LiveDrive: Selected (Red), Minimum position
Line2 LiveDrive: Selected (Red), Minimum position
CD: Not Selected (Red), Selected (Green), 75% position
Mic: Not Selected (Red), Selected (Green), 90% position
Video: Not Selected (Red), Not Selected (Green), Minimum position
Phone: Not Selected (Red), Selected (Green), Minimum position
IEC958 Coaxial: Not Selected (Red), Minimum position
IEC958 LiveDrive: Not Selected (Red), Minimum position
IEC958 TTL: Not Selected (Red), Minimum position
Aux: Not Selected (Red), Selected (Green), Maximum position
Capture: Selected (Red), Maximum position
AC97: Selected (Red), 50% position
SWITCHES
Headphone LFE: Not Selected (Yellow)
Headphone Center: Not Selected (Yellow)
Tone: Not Selected (Yellow)
3D Control Switch: Selected (Yellow)
Mic Boost (+20 dB): Selected (Yellow)
IEC958 Optical Raw: Selected (Yellow)
Mix: Selected (Red)
Mix Mono: Not Selected (Red)
External Amplifier: Selected (Yellow)
SB Live Analog/Digital Output Jack: Selected (Yellow)
Sigmatel 4-Speaker Stereo: Not Selected (Yellow)
Sigmatel Output Bias: Not Selected (Yellow)
Sigmatel Surround Phase Inversion: Not Selected (Yellow)
Mic Select: Mic1
Crucial settings seem to be Capture and AC97 (controls volume) in the Input tab, and the Mix setting in the Switches tab. So you may have to play with your mixer settings in your particular distro in order to get the application to work.
When I run the application and look at the system using the top command, the DTRC client typically uses only about 5% of the CPU. But running other applications, particularly network applications like Firefox and Thunderbird cause DTRC activity to come to a halt, although it may pick up somewhat if other applications are quiescent. By default Konqueror is the default browser in openSUSE 10.3, and that is what starts up to show the DTRC Status page when I start DTRC. Perhaps this reflects a performance issue on an old system, but it may be that DTRC just doesn't function too well with other applications running. It would be interesting to know what other Linux users with faster systems experience.
Hopefully, someone will provide some test results for the Mac version of CrossOver as well.
