Well, I assume that if it's not playing the pcm trigger will neither be called during suspend nor during resume, since the actual device suspend is later, this is only the pcm suspend. Actually, could the device suspend sleep and wait? Then we could play a sound during suspend if we somehow manage to make the audio device suspend last, and the pcm first :) johannes --=-+ufBX2XQFZWl99govrE/ Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIVAwUARUp4aaVg1VMiehFYAQL2iBAAlRRFvatKrxatJXP28J9dGMUj5x9mMKY8 g/CA4VJ/W2zqKSgXwL+UUCj9GK5fWfrY1JBAUvOuDngzdmgaH2/TY8pjIKr+ZQlH Djm4lWh/Qoe/vDlJv1QCDVj51pVMWILiOU0W4f0OB3YJED4HS72onJBm2YIRB+G9 IpMgusCdYF3VsKQoG6jik/f1cMytcITNxihXro47fAPzfcBtepPPjifU1wWXePjF tEmmZviNbrZZ3jGoSOxQ0oA5/lOsf3WpgplUbURjuTarHV8dbT/7G3pRmdGZrKWM FoPFbGbiRmIyW3/+0vrkuvFsib2wxzuseZ70uuRQ6J0kFzhckThwId9UNfVOTGNP Yp0v6yVxKKyykLFzI0qarn0n86nlQB2CqfEto+Yyk1f0enxChRqUWd3Okd+L1oys jfMKOt5fkQYfMA4CgkkWBY9Il3KVNgF2pXwSk4qsGauhgZy6WcAn2ByxChga+Jzn dgzFpZHe9Kh49px+VPoWvYaJGvxJcOIZgTlnd+8HI9h3iuVsTdP67CAB7obv4EpE IwOx45glv7dCF6zCfhRb9nx6/4SiA9UTQSbnNHOHj35CjCV/lmnlFrnXC5gQ3IZI c9lhA3dSI/0k+xoxjQEhBIJdKmte+UW3WV4+0PfV0OHNaoKnnk9AjJbxiRrfcewS uabVMBo6EhI= =1lV0 -----END PGP SIGNATURE----- --=-+ufBX2XQFZWl99govrE/-- --===============0010218991== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ------------------------------------------------------------------------- Using Tomcat but need to do more?
