The patch of the file patch_realtek.c fixes the speaker output on the HP ENVY Laptop 17-cr0xxx. The LEDs for muting the microphone and speakers still do not work. Likewise, the hotkey for microphone muting is without function.
This laptop model uses actually the Realtek ALC245 codec alongside with Cirrus Logic amplifiers. In the bios there seems to be no _DSD property specified in the ACPI tables of the CSC3551 section. Therefore, the file cs35l41_hda.c must also be patched.
Even if a patch of the file cs35l41_hda.c is excluded, it would make sense to make the adjustment in the file patch_realtek.c. then the sound output would work in case of a bios update on the part of the manufacturer.
