When porting a codec from kernel 2.6.32 to 2.6.37, getting this compilation error: error: 'struct snd_soc_codec' has no member named 'write' I see that include/sound/soc.h has really changed between those kernel versions. So, what other member of the struct s...
Alsa驱动snd_soc_read的底层实现 2015-01-27 22:43 −在分析snd_soc_codec_driver的结构体时,发现有些芯片的驱动中定义了字段reg_word_size, reg_cache_size, reg_cache_default,但没有定义read/write,如wm8993: static struct snd_soc_codec_dri... ...
Background: The snd-soc-dummy codec is a dummy codec used for testing and sometimes with i2s codecs that doesn't have their own driver. Example of use: https://github.com/skakri/asoc-i2s-loader/blob/master/asoc-i2s-loader.c It restricts ...
