ALSA: usb-audio: Fix card name for CVT Touch Device (1ff7:0f33)
PATCH 1/1 ALSA: usb-audio: Fix card name for CVT Touch Device (1ff7:0f33)
From: renpanpan <[email protected]>
The CVT Touch Device (1ff7:0f33) is a USB composite device (HID + UAC audio). Its iProduct string "Touch Device" is generic and does not identify the audio function. Windows names the audio function "MAXHUB Speaker" from the UAC OUTPUT_TERMINAL iTerminal descriptor.
Add a quirk entry to override the card shortname to "MAXHUB Speaker" with QUIRK_NO_INTERFACE to preserve normal stream and mixer creation.
