[PATCH 8/9] ALSA: hda/cs35l56: Fail if .bin not found and firmware not patched

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A tuning patch is always needed to enable the ASP audio port.
If the BIOS did not patch the firmware, then it is mandatory to
have a .bin file.
