Simultaneous capture on dmic and headset mic is having issue with high hw_level being reported. Issue Can be reproduced by: arecord -D hw:2,0 -f dat -d 60 /tmp/test0 & arecord -D hw:2,2 -f dat -d 60 /tmp/test1 & cat /proc/asound/card2/pcm?c/sub0/status Actual issue is : When we open one capture stream on one instance lets say I2S_SP and then once again if we open other capture on other instance lets say I2S_BT while first capture is in progress and when we try to read the status of both running instances by below command cat /proc/asound/card2/pcm?c/sub0/status we observe that avail_max is being doubled on first opened capture(I2S_SP in the example). This is because our previous implementation was like when any instance is opened it gets initialized in dma_open irrespective of on what instance it called open. For example: First I2S_SP called opened it initializes both SP/BT capture streams irrespective of on which instance the stream opened.next time I2S_BT called opened and it initializes both SP/BT this corrupts the behaviour . So with this patch the stream gets initialized only on specific instance when ever it gets opened calls hw_params. This rectifies the issue.
