Take two instances of Windows sound recorder from Accessories->Multimedia and record a file (on one of them). After recording is over, play the file. Now try recording on the other sound recorder while playing the first one. If you are able to hear the first recorded file, and the second one later (which you recorded while the first one was being played), your recording and play back would be working fine and you have full-duplex sound card installed in your machine.

The modem does not have the required hardware to perform this function without a Full duplex sound card. No special connections are required between the sound card and the modem. When the sound card and HSP modem are installed properly with all the correct drivers, the sound cards microphone and speakers will be used for the Speaker Phone feature. See similar questions...

With the current sound driver it's possible to have several SoundBlaster, SoundBlaster/Pro, SoundBlaster16, MPU-401 or MSS cards at the same time on the system. Installing two SoundBlasters is possible but requires defining the macros SB2_BASE, SB2_IRQ, SB2_DMA and (in some cases) SB2_DMA2 by editing local.h manually. It's also possible to have a SoundBlaster at the same time as a PAS16. With the 2.0 and newer kernels that configure sound using make config, instead of local. See similar questions...

No. The sound is an essential part of the game, and ST will refuse to run without sound support as described in 2.1. See similar questions...

The SignaLink SL-1 and SL-1+ only pass audio signals to and from the sound card, so they will work with ANY sound card that has a microphone input and a speaker output. The SignaLink Model SL-1+ also works sound card Line Input and Line Output jacks for greater flexibility. What you should really be asking is if the software will work with your computer and sound card. See similar questions...

In the formula, 9.6 is the interpacket gap time in micro seconds. 6.4 is the preamble+start-frame-delimiter time in micro seconds. Each time you send a packet, these are present. The 10,000 is the speed. You change this to 100,000 for 100 Mb/s ethernet. For full duplex, the formula is the same, but it applies to each channel. That is, full duplex is a point-to-point technology. If you connect nodes A and B. See similar questions...

Not necessarily having no sound is typically caused by one of the following problems and not related to a bad or damaged sound card. This can typically be adjusted by double clicking the speaker icon in the system tray and adjusting the volume or disabling the mute option at the bottom of the volume control slider if enabled.

Using good quality shielded cables and trying the sound card in different slots may help reduce noise. If the sound card has a volume control, you can try different settings (maximum is probably best). Using a mixer program you can make sure that undesired inputs (e.g. microphone) are set to zero gain. Philipp Braunbeck reported that on his ESS-1868 sound card there was a jumper to turn off the built-in amplifier which helped reduce noise when enabled. See similar questions...

Another variant is the beep program found at ftp://www.ibiblio.org/pub/Linux/kernel/patches/misc/modreq_beep.tgz The modutils package has an example program and kernel patch that supports calling an arbitrary external program to generate sounds when requested by the kernel. Version 2.0 and later of KDE allows playing a sound file for the console beep in KDE applications such as konsole. See similar questions...

Look in /etc/rc.d/rc.modules under the Sound Support section. There are several examples of modprobe lines for various sound cards. Yours may be listed. If it isn't, you can look in /usr/src/linux/Documentation/sound for specific sound card information. Once you have the appropriate modprobe line or lines for your sound card, add them to /etc/rc.d/rc.modules to have the driver load at boot time. See similar questions...

To be fair to all manufacturers we don't recommend sound cards. However, virtually any 7" PCI card will work as well as most USB and Firewire cards. Having the latest drivers is a bigger worry than wondering is a specific card will work with the MusicXPC. The best tech support we can offer is this: never use the drivers that come on the CD-ROM with a sound card. Train yourself to automatically go to the web to get the latest driver from the manufacturer's website. See similar questions...
