Audio read failed error

I am trying to run the GPSK31 application from the SuSE8 disks. When I click on any menu item in the application, it crashes out with this error: Using full duplex mode! *Audio read failed: File descriptor in bad state Xlib: unexpected async reply (sequence 0x434f8)! Segmentation fault The version which came with SuSE7.0 worked with no problem, but when I try to run that older version of GPSK31 with SuSE8, that crashes as well. Could anyone help, please? Many thanks Keith
