Dell Latitude E6530 laptop, lspci tells me: 01:00.1 Audio device: NVIDIA Corporation GF108 High Definition Audio Controller (rev a1) Subsystem: Dell Device 0535 ... Kernel driver in use: snd_hda_intel Symptoms: Audio works perfectly at boot, and for some amount of time after. But somewhere around 6-8 hours of uptime, it gets into a strange state where I'll get no audio... and then it will cut in for all of 2 seconds or so (fairly consistent, that part), and then cut back out for anywhere from 10 seconds to a minute, then another 2 seconds of sound.. lather rinse repeat. Before I start the thankless task of bisecting this (which means I'll be able to do only 1, *maybe* 2 steps a day), does this ring any bells? --==_Exmh_1428021275_2118P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Exmh version 2.5 07/13/2001 iQIVAwUBVR3gGwdmEQWDXROgAQISYg//fArsUhXiY+hWW8vKUVkNbDwBxeqByXXU 3QUY/dvIEAERrg0o4CO8kwmgFlb93erRn7oXMzHnqRQtoai/xABSWUVY8QB6RcXd Ez7wgE7qyHxu3TjTyoESlyDJkkAiqbczzyEMhJ1c85CWFHEbUifScNnGO3g58uPh E7jk7rznaHEXeszmaETYfx8QNQhAQC3WP+LrunYANSw17QA1/I23xMQpmchAnlcH En6nT5Eoj1nWRccQmI1okeu6pQpJH/v76QamhrerFPchKG0BuK+GhzREkpMCuZ20 QQlkRbXxaytfQaq3CLRmQFrhWrsJi4Fskdwhv7MzWID5bcnjxOP+TssmwjhGn0F9 KmRvHND4AqB94O+qdnYyYdHeKzksCKoU4292GOgoWzjpB3vxZ9lbOuGka1aKxdQ7 /w9XBQlA0pln9o3ne8bDPIrsDrcvmlKbCDId7ablklOTgEp73NMRJlIEfuASGb9T ghDmFVBqqcX3JWGh3Zgp6HtIOAvcbC4tpLEAorgMDn7b4vN+AKCyOfRIAv5Q9Cxn ZVkvETo+KqWU3keR8Y18aqub+Jo0DAlCa/agQeO0a2JOgdHA6MRY8x6KplGxP4V0 q2SDYKhT2eEVzqPV044TXso7Cb2iqaqTbg+N9uwhXzpvoDNNv1q1MJ08WnXSHMnr aLYteQJYTvo= =cBB8 -----END PGP SIGNATURE----- --==_Exmh_1428021275_2118P--
