[64studio-devel] [64 Studio] #287: Possible kernel regression

[Dick Wright]

Hello Daniel

That is not the culprit I'm afraid. It was the first thing I looked at. 
I have checked again. Interestingly, even when jack will not connect at 
96k, it resets the clock rate as shown in Envy Control to 96k from 
wherever it was last set.

I wonder if it is related to the on-board sound chip, an AC97. Although 
it is disabled in the BIOS, numerous references to it appear in the 
installed kernel module names. The only reason I have for this suspicion 
is that the AC97 operates at 48k only and when my machine has been 
rebooted it will only work at 48k and below. However, listings of the 
modules (lsmod) after rebooting show no difference to those after 
reinstalling the alsa modules.
As I reported earlier, 96k sound does not work after booting but does 
after reinstalling alsa modules; until the next re-boot.

Regards

Dick
