It started in the late 3.4.x kernels. Sound works on boot and for 5-10min after, then the speakers stop working at all.=20 I posted a while back on the alsa-users list, and someone else had the same issue:=20 http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28769.html It seems that the speakers(?) are getting moved to state D3 and turning off. You can manually get it to come back for a few minutes by using hda-verb to move it back to D0:=20 hda-verb /dev/snd/hwC0D0 0x1f SET_POWER_STATE 0 http://www.alsa-project.org/db/?f=3Dfd5ca157b2e76942df5ce2f0ae1a2817f3f08afd is my alsa-info.=20 I'd file a bug on the alsa bug tracker, but it still seems to be down (for many months now?). No response on alsa-users, so now that I have a bit of time, I am posting here in hopes someone can look. ;)=20 Happy to provide more info or try things.=20 kevin --Sig_/BVzIUtwM8a0.7BCgYrv9jaN Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQIcBAEBAgAGBQJQ1iTPAAoJEEs3sNgP+7teP7kQAJV/L7VxhlrQhN2iHXtefqwO xWcMgO4+MLzf37wBS7aKoFO5QxdmfpxgY0fyPZ0hZq4XHCRCY/FQTFZzdKMP8SOA +1T5RWYbN8s3INL94zqXVwESHQyAguD6N4bLeGvmpb3iQHhkNLlLrEstJ0W6bXGS qd19CHm3Fm3iULnJ777LrLoE+f3bmocAwvyveE5r/tkn6jVQ4+oh7awQeWRYWNWP 7m6fuukpKzyZATSCDkvQjRQm9PLUwwt5Vw/S6fp2eUaNx1QugxLCk4vhHmcBRPH9 VAvtskzjQRK5hhCGtJzMJGSO6MTDAX7O1InyXQcl7F0LGyZyrddArL1aE3xk+rpE hEhVe7ABlLl5y5O2NRdeoLOo+NATdLDgdncE1QEkeBS43WUNUz9UXSoMIX3a/XgV cklm9Q56NVdturUKb322rfMl91dACZQfBiNRoRgZFsIvLRxjgRD3IsOPS/gtehLx xk3XL18fXfF93Cx2lpG7P1jPyb6Ew2GsSbhXmz4Y7iWkhGEmzOJxeF0vKFAewdKR ob7Je2tnXz7k1bjM5QN46MpebZcY+gfQ8fTOfTFrRSsJpFtgc7kKiD3x7cZHyP0Q iHc3d9jWo9QsZO25Y9QiF7EvN5/xY4XqeuPYuZqO9c+6igwWeYSwXNCo/ugaHick 1WRHaoMtMC7ivMKdN8Uk =z1/O -----END PGP SIGNATURE----- --Sig_/BVzIUtwM8a0.7BCgYrv9jaN--
