[ Upstream commit fc6f923ecfa2fafd0600f1b7e2de09baf29865e2 ]
Track the converters handling the silent stream using a new variable to avoid mixing of the open/close and silent stream use. This change ensures the proper allocation of the converters.
Fixes: 5f80d6bd2b01 ("ALSA: hda/hdmi: Fix the converter reuse for the silent stream")
