Potential Audio Issues - HP Xw460c - ProLiant - Blade Workstation User Manual

Quality—This pull-down menu allows the local user to select one of three different audio quality settings:
•
Low—Specifies a sampling rate of 11 kHz.
•
Medium—Specifies a sampling rate of 22 kHz.
•
High—Specifies a sampling rate of 44 kHz, which is equivalent to CD quality audio.
•
Higher quality audio (and its higher sampling rate) requires more network bandwidth, and can impact the
performance of RGS, especially over bandwidth-constrained networks.

6-2-5 Potential audio issues

Several potential audio issues are described below along with their potential causes.
No audio on Windows Receiver—Verify that your Local Computer audio device is working. The volume
•
control slider on the Receiver should play the default beep when released. Ensure that the Speaker Button on
the Receiver Control Panel is not in the mute position. Refer to the Windows Sender Audio Installation
section for information on selecting the mixer as the input line. Refer to Section 6-2-2,
the Sender," for information on how to ensure the volume levels are not too low. Make sure that mute is not
enabled on the Wave line of the Sender or Receiver Volume Control.
Audio not continuous—Low bandwidth connections can cause discontinuities in the audio stream. Reducing
•
the quality and turning off stereo may improve the audio quality. Some high priority CPU intensive tasks may
disrupt the audio stream. The Windows Task Manager may help you identify such a task. Another possible
problem may be a bad network setup.
PC speaker sounds not working—The Sender captures all audio information sent through the mixer. This
•
includes most audio alerts, MIDI, Direct Sound and Direct Music. Sounds generated by the PC speaker are
not captured by the Sender and will not be transmitted.
Audible pops and glitches in sound—This is most likely because the network bandwidth or system resources
•
are starving the audio streaming from continuous play.
Try a lower audio quality setting to reduce network bandwidth usage.
•
Be sure you system is not doing something so computationally intensive that it is starving RGS from
•
keeping up with graphics and audio processing.
Enabling audio causes continuous network traffic—When the Sender detects an audio signal, that signal is
•
sent to the Receiver. If the audio device on the Sender is silent, there should not be any network traffic due to
audio. If the audio device is generating a large amount of noise, that noise may be interpreted as an audio
signal, and be sent to the Receiver. This may occur when something is connected to the "Line In" port of the
audio device. Reducing volume levels or disconnecting any external devices may help reduce the
interference.
ToggleKeys sound not working—The Accessibility control in Windows will play a sound when some control
•
keys are pressed. This sound is not heard on the Receiver because it is played through the PC Speaker. See
the section "PC speaker sounds not working" above.
No audio with multiple audio devices—The Sender will open up the device that is registered as the default
•
audio device. The Sender is a service that is running in a different context. If you have multiple audio
devices, it may choose a different device than you have selected as the default. Disable the extra audio
device to ensure the Sender uses the correct device. See the Windows Sender Audio Installation section to
set up the audio device after disabling the extra audio device.
