From: Patrick Lai <plai@codeaurora.org> [ Upstream commit 9f169b9f52a4afccdab7a7d2311b0c53a78a1e6b ] When multiple front-ends are using the same back-end, putting state of a front-end to STOP state upon receiving pause command will result in backend stream getting released by DPCM framework unintentionally. In order to avoid backend to be released when another active front-end stream is present, put the stream state to PAUSED state instead of STOP state.
