Hi, something strange with it. When I compile kernel without loadable module support (# CONFIG_MODULES is not set) it works.

Hi everybody, would be someone so kind and help me with my sound card? My connection is: cpu AT91SAM9G25 I2S (SSC0) --> codec TLV320AIC3106 <-- clock 12MHz Codec is clock master.

In kernel 5.12 it worked fine, but I can't make it in either 5.15 or 5.17.
dmesg doesn't help at all, even with debug compilation switch: ... [ 1.203333] ssc f0010000.ssc: Atmel SSC device at 0x(ptrval) (irq 22) ... [ 1.616666] atmel_spi f0000000.spi: Using dma0chan2 (tx) and dma0chan3 (rx) for DMA transfers ...

The only difference in 5.12 is: [ 3.869999] ALSA device list: [ 3.876666] #0: TLV320AIC3106
So, what's wrong? Thanks Jiri
