Hard coded coefficients to make Huawuei Matebook X right speaker work. The Matebook X has a ALC298, please refer to bug 197801 on how these numbers were reverse engineered from the Windows driver The reversed engineered sequence represents a repeating pattern of verbs, and the only values that are changing periodically are written on indexes 0x23 and 0x25: 0x500, 0x23 0x400, VALUE1 0x500, 0x25 0x400, VALUE2 * fixes bug 197801 * skipped reading sequences (0x500 - 0xc00 sequences are ignored) * static values from reverse engineering are used Signed-off-by: Tomas Espeleta <tomas.espeleta@gmail.com> --- sound/pci/hda/patch_realtek.c | 70 +++++++++++++++++++++++++++++++++-- 1 file changed, 67 insertions(+), 3 deletions(-)
