[BUG] [TGL] WOV capture fails for the second time on TGL Chrome DUT #2511
Description
Describe the bug
WOV capture fails for the second time.
To Reproduce
1)Start the WOV capture:
arecord -Dhw:0,7 -M -N -c 2 -f S16_LE -r 16000 --buffer-size=64000 tmp.wav -vvv
2)Start tapping on the DMIC and the WOV capture starts.
3)Press Ctrl+C
4)Second time start the WOV capture.
localhost ~ #
tmp.wav -vvv arecord -Dhw:0,7 -M -N -c 2 -f S16_LE -r 16000 --buffer-size=64000
Recording WAVE 'tmp.wav' : Signed 16 bit Little Endian, Rate 16000 Hz, Stereo

This capture shows failure. From the failure logs, it looks like the first capture stream did not freed
completely.(The allocated stream1 is not freed) and hence the second time capture does not start.
