Is it normal to have so many hda_codec_cleanup_stream  ?

The HDA controller seem support multi stream capture

[ 6.748965] hda-intel: chipset global capabilities = 0x4401

Two stereo ADCs support 16/20/24-bit PCM format, multiple stereo recording

but the driver only create 1 capture stream.but two capture volume/switches
and input sources
