TAS5805M: There is no sound when playing music in TDM mode ...

TDM in TAS58XX family is using rising edge of FS/LRCLK as a TDM frame start signal. But your data begins with the falling edge. So you have two choice: 1. Change the TDM format in your SOC to rising edge as TDM beginning signal. 2. Configure register 0x34 to shift suitable bit. Such as 16ch, 32 bit TDM signal, you should shift 16*32/2 =256 bit ...
audio - How does a channel know to drive in I2S TDM mode ...
https://electronics.stackexchange.com/questions/528900/how-does-a-channel-know-to-drive-in-i2s-tdm-mode
I understand TDM mode would allow the Controller (Master in legacy terms) to read N channels on the single bit serial data line (as shown in the picture). However, I don't understand how the audio device knows when to drive the serial data line with its data. How is contention avoided?
PCM1864: TDM Mode - Audio forum - Audio - TI E2E support ...

The PCM1864 is able to operate in TDM mode; when this format is used, the bit clock should have a frequency of 256×Fs, this value is fixed for this device. Given that said, the number of channels available on the TDM stream is determined by the data size, for example, if 32-bit word length is used, up to eight channels would be available.

TDM for 16 audio channels. What's the best way? - Q&A ...

So you cannot send only one channel on an I2S signal. In TDM mode you would have all four on the bus so treat them however you like. Yes, you can daisy-chain two of these codecs to give you 8 ADC channels and 16 DAC channels. Then use another pair for the other 8 ADCs and 16 DACs. Now I would recommend that you operate the part in TDM 8 mode.

I want to work in TDM mode with 4 outputs but have difficulty understanding the register configuration. Some details: I have an external clock which delivers 25MHz to MCLK, external clock of 12.5MHz to DBCLK, and an external DLRCLK of 48.8kHz.

TDM format, sending more than 2 channels in same Word-Select period is possible. In TDM format, Word Select’s width is only 1 bit clock long. TDM mode is usually used when more than one slave is connected to the bus, in which, master sends data for all slaves using same synchronization (word-select) line. Every slave is configured to use their
