Recently we set CONFIG_SND_HDA_POWER_SAVE_DEFAULT to 1 when configuring the kernel, then two machines were reported to have noise after installing the new kernel. Put them in the blacklist, the noise disappears.

https://bugs.launchpad.net/bugs/1821663 Cc: stable@vger.kernel.org Signed-off-by: Hui Wang hui.wang@canonical.com --- In the V2, put the Intel entry in the blacklist according to pciid's order, and change the machine name "Intel Laptop 8086:2064" to "Intel SDP 8086:2064".
