Agreed and thats why we were planning to use the ioctl to determine the sound drv version but somehow ioctl returns failure and not something we would want to rely on. ioctl(spcm->poll_fd, SNDRV_PCM_IOCTL_PVERSION, &ver); Also our product VMware workstation is supported on wide range of Linux operating systems and so we don't want to restrict with snd drv version > 2.0.8 Thanks, Bankim. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
