Description Caleb Crome 2009-07-08 20:23:46 UTC

Part of what made https://bugs-archive.lyrion.org/show_bug.cgi?id=12456 difficult to diagnose, is that codec_reg seems to return the values from the cache, rather than reading the actual device.  

It should read from the device I think.

No, we should fix it so the cache is correct.

Comment 2 Caleb Crome 2009-07-13 08:22:41 UTC

Hey, I really need some way to verify the actual settings in the device.  can we make a new thing like codec_reg_nocache so I can verify cache vs. nocache?

r6538 added debug to aic3104 registers. You can print the register settings using:
	cat /sys/bus/asoc/drivers/aic3104-codec/debugreg
