-## Case Name: Run multiple pipelines for capture
-## Preconditions:
-##    check-capture-10sec pass
-## Description:
-##    Pick up pipelines from TPLG file for max count
-##    Rule:
-##      a. fill pipeline need match max count
-##      b. fill pipeline type order: capture > playback
-##      c. if pipeline in TPLG is not enough of count, max count is pipeline count
-## Case step:
-##    1. Parse TPLG file to get pipeline count to decide max count is parameter or pipeline count
-##    2. load capture for arecord to fill pipeline count
-##    3. load playback for aplay fill pipeline count
-##    4. wait for 0.5s for process already loaded
-##    5. check process status & process count
-##    6. wait for sleep time
-##    7. check process status & process count
-## Expect result:
-##    all pipelines are alive and without kernel error
