Re: [PATCH] ALSA: usb-audio: Fix regression with Dell Dock jack detection

The recent commit added Jack controls to Dell Dock, but it added with iface = SNDRV_CTL_ELEM_IFACE_CARD. Unfortunately this doesn't match with the changes in user-space UCM profile, which expects iface = SNDRV_CTL_ELEM_IFACE_MIXER as default. This mismatch resulted in the non-working profile, and the Dell Dock is gone on pipewire / PulseAudio after the kernel update.

Fix the regression by adjusting the iface of the new ctl elements to *_MIXER.

Hi Takashi,

UCM expects SNDRV_CTL_ELEM_IFACE_CARD for jacks by default. Which change do you refer? I would drop this patch.

Thanks, Jaroslav
