Dear all,
Recently I sent some patches to add support for a new board based on AM335x processor [1]. The board has the TLV320AIC3106 audio codec, the MCLK signal is provided by an external oscillator of 12MHz. The problem is that when I play a wav file for example I heard the song a double speed. This is with v4.0 and current mainline.
In dts file I defined "ti,codec-clock-rate = <12000000>;" which is the correct value. Curiously when I changed the clock rate value to 24000000 I heard the song at normal speed. AFAIK the correct value for clock-rate is 12MHz so I suspect that something is wrong in the driver, maybe it sets a wrong clock divider/multiplier ? Anyone can point me in the right direction to fix the issue ? I see that am335x-evm and am335x-pepper boards also uses this audio codec, did anyone with those boards have the same problem?
