Hi, spujar,

  • I have changed MCLK to 2.8MHz, but it doesn’t work , The default clock is 11.30MHz,when I play music on the command line, it becomes 12.30Mhz

  • cmdlineis : speaker-test -D hw:es8316tegra,0 -c 2 -r 48000 -F S16_LE -t sine -f 500
    still no sound .

  • Codec as the master mode ? Can I modify it this way? It’s still 11.30MHz.
