Thanks Erich,

I've now tested "SmallDV" with available now USB audio devices:

Creative Sound Blaster Play! 3                                       $35 AU   
available world-wide

ASMedia HS100-B chipset Volans VL-UA01               $20 AU

The "Play! 3" has stereo mic input. Decoded audio is slightly better.

The Volans only has mono mic input.

Both definitely better than the "el-cheapo" C-Media C119 USB audio devices.

Though, these do have LED outputs and Vol Up, Down and Mute inputs.

(I and others thought useful for repeater controllers)

"SmallDV" uses only one audio device so, cannot get into buffer problems 

because of different sample rates, in and out.

The long and short of this, don't be afraid to try another USB audio device.

Problems may not be with the software.

Keep smiling
