Subject: [PATCH v20 38/41] ALSA: usb-audio: qcom: Use card and PCM index from QMI request
Date: Thu, 25 Apr 2024 14:51:22 -0700 [thread overview]
Message-ID: <20240425215125.29761-39-quic_wcheng@quicinc.com> (raw)
In-Reply-To: <20240425215125.29761-1-quic_wcheng@quicinc.com>
Utilize the card and PCM index coming from the USB QMI stream request.
This field follows what is set by the ASoC USB backend, and could
potentially carry information about a specific device selected through the
ASoC USB backend. The backend also has information about the last USB
sound device plugged in, so it can choose to select the last device plugged
in, accordingly.
