The following issue has been RESOLVED. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1231> ====================================================================== Reported By: Tobias Diedrich Assigned To: ====================================================================== Project: ALSA - lib Issue ID: 1231 Category: 0_general Reproducibility: always Severity: minor Priority: normal Status: resolved Resolution: fixed Fixed in Version: ====================================================================== Date Submitted: 07-04-2005 16:30 CEST Last Modified: 07-09-2006 13:44 CEST ====================================================================== Summary: Sharing soundcard via dmix does not work when mixing 32bit and 64bit applications. Description: I have configured a friends AMD64-System to use dmix by default. I also made the same configuration for the 32bit-chroot and made sure that /tmp is a bind-mount, so the dmix-Socket is shared between 32bit and 64bit applications. However while sharing between one type of applications (either all 32bit or all 64bit) works fine, mixed sharing doesn't work. A strace shows that the socket is opened by apparently communication fails. I suspect that the structures passed by dmix have problems with differntly sized fields between 32bit and 64bit. ====================================================================== ---------------------------------------------------------------------- tiwai - 07-08-05 12:00 ---------------------------------------------------------------------- Yes, it's incompatible between 32 and 64bits. The struct shared in shmem doesn't match. snd_pcm_direct_share_t in pcm_direct.h defines the shared struct and the size of snd_pcm_[su]frames_t is long, so it depends on architecture. Also, we should be careful about alignment, too... ---------------------------------------------------------------------- ikonst - 08-18-05 22:29 ---------------------------------------------------------------------- Same as bug 0001336 which I've filled and is indeed resolved in CVS (I've just checked). Please mark as resolved.
