Well, this is embarrassing: Since this began I switched the machine on |
11 |
even less often than before, but yesterday I found out by chance that |
12 |
the sound did not come from the internal speaker but from the speakers |
13 |
built into my screen. Now I traced it to the snd-hda-intel kernel module |
14 |
(noise there if loaded, sound gone when removed with |modprobe -r|). |

Why was the sound never heard on bootup in 3.8.x kernels but is starting |
17 |
with 3.10.1? |

P.S.: At least now I know that the easy workaround is to tune the |
22 |
(hardware) speaker volume down to 0... |
