https://devzone.nordicsemi.com/f/nordic-q-a/123478/ticking-problem-between-nrf52832-and-tlv320aic3104Hi, I am currently integrating nRF52832 with TLV320AIC3104 codec. I have successfully initialized I2C and I2S communication between the two boards and configured nRF52832 as master and TLV320AIC4104 as slave . These are my current I2S settings: i2s_cfgen-USTelligent Community 13Wed, 06 Aug 2025 08:25:24 GMThttps://devzone.nordicsemi.com/thread/544727?ContentTypeID=1Wed, 06 Aug 2025 08:25:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4abcfbee-de08-423f-a8ef-91cabd9e0611Kenneth<p>The buffer size I am thinking of is the audio buffer size for each i2s transfer, which I suspect is what I can see between the red lines here:</p> <p></p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/6131.Capture.PNG" alt=" " /></p> <p>Increasing that should allow less constraints on how frequently you need to update the i2s transfers, in this case almost looks like you miss or skip some buffers.</p> <p>Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/544716?ContentTypeID=1Wed, 06 Aug 2025 05:38:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ee6c6b7e-3a04-4e4b-a545-a73df9e595bfOm Agrawal<p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1754458685183v1.jpeg" alt=" " /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/544715?ContentTypeID=1Wed, 06 Aug 2025 05:38:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:56a2bab1-731c-4616-a65d-80b79fbdf5deOm Agrawal<p>Hi,<br />I am currently implementing Direct Digital Synthesis(DDS) algorithm for producing different pure tones and my I2S_Word Size is set to 16bits.<br />I have also checked the output via an osiclloscope and I am attaching the image for your reference.<img style="max-height:0px;max-width:0px;" src="https://devzone.nordicsemi.com/resized-image/__size/0x0/__key/communityserver-discussions-components-files/4/pastedimage1754458577961v1.jpeg" alt=" " /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/544600?ContentTypeID=1Tue, 05 Aug 2025 11:20:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a8ac2dc8-df3e-4372-8768-28e18e33eacfKenneth<p>Hello,</p> <p>What is the block size used here? Have you tried to increase the size of it?</p> <p>Have you any measurements of the audio? e.g. if you play a 1kHz test tone, what does the audio sound like (it can tell us something about the duration of the noise).</p> <p>Kenneth</p><div style="clear:both;"></div>
