Hi, I have a RT5350 module with wm8978 codec and try to driver sound under openwrt. The relevant driver in openwrt trunk as follows: sound/soc/ralink/mt7620-i2s.c sound/soc/ralink/mt7620-wm8960.c drivers/dma/ralink-gdma.c The i2s integrated by RT5350 is same as the one of MT7620. So I use the file "mt7620-i2s.c" directly and write a file "rt5350-wm8978.c" as alsa machine driver. After modifying several configs, I build the image and flash it intomodule. The kernel have found sound card on booting, initialized it successfully. But when I play a wave file, the codecwork badly. The wave file should sound "rear..left", I heard "left...left". I guess that there are something wrong in data transmission. Now I want to check the mt7620-i2s and ralink-gdma drivers. Does anyone have used these drivers? Or does anyone runmt7620-wm8960 group? Any response will be very appreciated!
