Fedora 15 64bit Kernel update breaks [some] hardware usage

[The Duke]

Hello,

I recently installed Fedora 15 x86_64 on two machine,
The first machine (@home) is equipped with a VIA VT2020 sound codec, sound card correctly detected and works fine with kernel "2.6.38.6-26.rc1.fc15.x86_64"
The second machine (@work), equipped with a Haupage WinTV 4000, card correctly detected and works fine with Kernel "2.6.38.6-26.rc1.fc15.x86_64"

Then I updated both machines and now the kernel is "2.6.38.6-27.fc15.x86_64":
On machine 1: The sound no longer works
On machine 2: The card is detected, but kernel module refuses to load,

Any one have similar problems after this kernel update ?
Any one with solutions ?

Thanks !

Any help ?

Well, got the solution:
launch alsamixer,
choose the HDA sound card with F6,
Go to "Independant HP" option and set it to "off"
