imx6q android4.4.2 audio 49.6kHz

[liu_jialu]

use SSI1 to be I2S, i made a dummy sound card to force output audio, but the audio frequency is not 48kHz, but 49.6kHz. and blck is not 3072kHz, but 3172kHz.

where should i check, please give a advance, thanks.

and i change the ssi_clk parent from "pll3_pfd_508M" to "pll4_audio_main_clk" in arch/arm/mach-mx6/clock.c, got the same result.

Hi 家禄 刘 

please refer to Chapter 8 Porting Audio Codecs to a Custom Board

attached Porting Guide, probably parent pll value should be adjusted for

produced accurate audio frequency clock.

Best regards
igor
