Can you guess what the problem was!?!?? Some time ago I installed a wrapper lib for alsa to run oss apps on alsa instead of using the kernel compat layer. I guess the alsa-oss package need to be recompiled against the new libc6 I had that libalsatoss.so.0 library preloaded: [EMAIL PROTECTED]:~$ cat /etc/ld.so.preload /usr/lib/libaoss.so After commenting it out and running ldconfig the problem disappeared. Below output from ldd /bin/bash from before and after the action: Before: [EMAIL PROTECTED]:~$ ldd /bin/bash /usr/lib/libaoss.so (0xa7f18000) linux-gate.so.1 => (0xffffe000) libncurses.so.5 => /lib/libncurses.so.5 (0xa7ebe000) libdl.so.2 => /lib/libdl.so.2 (0xa7eba000) libc.so.6 => /lib/libc.so.6 (0xa7d9f000) libalsatoss.so.0 => /usr/lib/libalsatoss.so.0 (0xa7d96000) /lib/ld-linux.so.2 (0xa7f1f000) libasound.so.2 => /usr/lib/libasound.so.2 (0xa7cd4000) libm.so.6 => /lib/libm.so.6 (0xa7cb0000) libpthread.so.0 => /lib/libpthread.so.0 (0xa7c5d000) After: [EMAIL PROTECTED]:~$ ldd /bin/bash linux-gate.so.1 => (0xffffe000) libncurses.so.5 => /lib/libncurses.so.5 (0xa7eb1000) libdl.so.2 => /lib/libdl.so.2 (0xa7eac000) libc.so.6 => /lib/libc.so.6 (0xa7d91000) /lib/ld-linux.so.2 (0xa7f0b000) [EMAIL PROTECTED]:~$ sudo dpkg -i Desktop/libc6_2.3.6.ds1-2_i386.deb (Reading database ... 175620 files and directories currently installed.)

Knowing the above you can look into it more approperly and perhaps fill-in another bug against libaoss Greetings -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
