hi Guys, Regarding my earlier mail. ////////// FC7 hangs on SB16 I have Biostar M7VKQ mother board with built in sound card AC'97 2.2 Audio CODEC. There is also an external sound card Sound Blaster 16 which I have attatched. The problem is that the onboard sound card is working fine. It is when I make the SB16 sound card work by making it default that the audio plays for some time and the FC7 hangs. I then have no option but to do a hard reboot I tried reinstalling the latest version of ALSA drivers/ utils/ lib packages but have had no luck. Would apperciate any solutions given ////////// I tried the 'Repeat' play option in 'Soundcard Configuration' tool. During this the system never hung. I thought this may help to understand the defect better. If it is concluded that it is h/w pblm. then kindly let me know how can it be avoided if any. Thanks in Advance......... -- Thanks, Regards, Ragavendra. -- Take Care, Regards, Ragavendra.
