		*BuenaVista FAQ*



			Q: What is the slider in 'Audio Tool' for? A: Slider selects the send/receive switching level in half-duplex mode. If you have 'auto' switch on, BuenaVista Audio Tool automatically switches between sending and receiving audio. If the level of received signal is higher than the slider position and the level of microphone signal is lower than this position receiving mode is active (you cannot talk). Otherwise, sending mode is activated and you are not able to hear the incoming signal. Q: How does the 'auto' switch work? A: 'Auto' mode enforces automatic switching between signal sending and receiving. Refer to the previous question for detailed description. When 'auto' mode is off and you have full-duplex audio card (capable of playing and capturing audio at the same time), application uses this mode. Otherwise, you need to switch between send and receive manually (pushing the mic/speaker button). Q: Why don't I hear other conference members? A: There may be two major reasons for that – incorrectly configured audio card or a session status problem. You can distinguish between those two observing the speaker level indicator on the main panel. If it displays changes in the incoming stream level, the problem is caused locally probably by the audio card configuration or speaker/headphones connection. Please, refer to the audio card configuration section for details. Q: Why does audio sound choppy or clipped? A: Today's Internet is not well equipped for distribution of the real-time multimedia streams. Thus, such problems might be simply caused by network congestion or delays. The only thing that can be done is minimizing the bandwidth by choosing 'Modem 28.8' connection on General Options panel. You can inspect the system performance data in the "Statistics" panel. If the number of late or lost packets exceeds 5%, you have a serious network performance problem. Another possible cause of clipped audio is too high a setting of the microphone cut-off level on the sending participant machine. If some segments of his speech signal fall below this level, they are classified as silence and skipped. Please, instruct this participant to lower the threshold levels.
