Hi,

Please post the Linux log file. Also provide information about your bitrate clock frequency, sound format and the file format that you are trying to play.

HI, we are using TLV320DAC3100 audio codec. MCLK = 24MHZ ; BCLK = 1.5MHZ(actually it should be like 1536000 , but due to 24MHZ we are getting 1.49MHZ). and the wclk and DIN we are getting according to the data. host is Am3352.

boot log i am posting because -- codec is loading and necessary events are generating -- if those are required i will post audio related.

In the tlv320dac31xx.c :

in the function : aic31xx_setup_pll : this is mentioned.
if (bclk_score != 0) {
dev_warn(codec->dev, "Can not produce exact bitclock");
/* This is fine if using dsp format, but if using i2s
there may be trouble. To fix the issue edit the
aic31xx_divs table for your mclk and sample
rate. Details can be found from:
www.ti.com/.../tlv320aic3100.pdf
Section: 5.6 CLOCK Generation and PLL
*/
}
do we need to change any thing -- with I2S -- ?? i think yes -- there is change in clocks -- might need to change..the parameters in aic31xx_divs array

Viswa.

Hi Biser, McASP expert also OK. But our case is we are getting all required clocks to the codec INPUT.But the registers values in the codec are not configured correct : as we are using aic31xx.c for dac3100.c .

one more doubt -- for audio codec related help -- do i need to post in Audio Amplifiers fourm -- is it OK to post in this fourm.
we like to conform the Audio codec register configuration values 1. After bootup 2. during playback(START) 3. once playback is STOP

regarding codec configuration : HPL , HPR and SPK -- can we enable both in the same time atleast for testing
generally : one(SPK) is active and the other(HPL, HPR) will be in inactive. can you please conform this point.

regards,

Viswanath K.
