For passthrough PCM, we can only support the SSP DAI format as PCM capabilities.
On BYT, pulseaudio will try 16bit wav on 24bit pass through PCM. And it will fail since no enough data is passed to DAI. And S16_LE format should not be supported by this 24bit pass through PCM.
Hi Liam,
Is my understanding on pass through pipeline is wrong?
Passthrough pipeline cannot change any audio parameters like rate, format etc, it just passes the data straight through from PCM to DAI (or vice versa).
