Subject: ac97_codec/es1371 screwy on 2.3.46-2 (pre)
Date: Wed, 16 Feb 2000 01:06:19 +0000 [thread overview]
Message-ID: <marc-linux-sound-95067371116782@msgid-missing> (raw)
I'm still getting weird oopses when trying various mixer programs with the
es1371, on kernel 2.3.46-2, with sound drivers compiled as modules.
Attached is an example - still obviously a
problem with the ac97 implementation w/ es1371. I'm still not quite sure
why ac97_codec is being used in the first place.
