Hi @schreibfaul1 , I just updated to your last commit and I'm getting this error every time I run a radio that has SSL, I have a

CONFIG_MBEDTLS_EXTERNAL_MEM_ALLOC=y

I think the reason for this will be that I have increased the DMA memory for I2S.
This is better for m3u8 streams. When a new file is fetched, the sound only runs over the supply in the DMA memory.

If you have enough, you can reduce it to half again.

CONFIG_MBEDTLS_EXTERNAL_MEM_ALLOC=y is a much better idea. But I think this is only possible via the menuconfig.

"Component config" --> "mbedTLS"--> "External SPIRAM"

I applied the following settings and it started working again, I think these settings are the ones recommended for listening to web radios excluding m3u/m3u8:

m_i2s_chan_cfg.dma_desc_num  = 16;                     // number of DMA buffer
m_i2s_chan_cfg.dma_frame_num = 128;                    // I2S frame number in one DMA buffer.

CONFIG_MBEDTLS_EXTERNAL_MEM_ALLOC=y
Yes if you use the Esp32 platform but if you are using the pioarduino as a platform, you can use it like this:

[env]
framework = arduino
platform = https://github.com/pioarduino/platform-espressif32/releases/download/54.03.20/platform-espressif32.zip
....
.....
....

custom_sdkconfig = CONFIG_MBEDTLS_EXTERNAL_MEM_ALLOC=y

[env:esp32dev]
board = esp32dev
