Missing initializer for ext_clk_freq_hz (IDFGH-14501)

[floitsch]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

The I2S_STD_CLK_DEFAULT_CONFIG macro is not initializing the field ext_clk_freq_hz which is available on SOC_I2S_HW_VERSION_2. When compiling for platforms with that hw-version (like the S3), there are now warnigs:

warning: missing initializer for member 'i2s_std_clk_config_t::ext_clk_freq_hz' [-Wmissing-field-initializers]

#define I2S_STD_CLK_DEFAULT_CONFIG(rate) { \

@floitsch Thanks for reporting! May I ask your environment? Arduino or using idf.py directly?

idf.py directly.

I applied the fix, but the error

i2s_std.h:220:1: error: designator order for field 'i2s_std_clk_config_t::ext_clk_freq_hz' does not match declaration order in 'i2s_std_clk_config_t'

Do you need to change the order ?

.ext_clk_freq_hz = 0,
.mclk_multiple = I2S_MCLK_MULTIPLE_256,
