(this value is actually hard-coded in the TDA998x driver) I had a look again on the tda998x driver from NXP and the linux tda998x driver: - the NXP driver handles the TDAs 19989, 19988, 9984, 9983 and 9981. It accesses the tda registers only at I2C address 0x70 and 0x34 (hard-coded values in the driver). - the linux tda998x driver handles only the TDAs 19988 and 19989. As we have no documentation about the chips TDA 19988 and 19989, may the HDMI I2C addresses of these chips be different from 0x70? -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
