Many X86 devices using a BYT SoC + RT5651 codec are cheap devices with generic DMI strings, causing snd_soc_set_dmi_name() to fail to set a long_name, making it impossible for userspace to have a correct UCM profile which knowns which input is connected to the internal mic, which input is connected to the hsmic (for correct jack-based switching) and which inputs are unused. Our quirks already specify which inputs the internal and headset mic are connected to. This commit sets a long_name based on the quirks so that userspace can have UCM profiles doing the right thing based on the long_name. Note that if we ever encounter the need for a special UCM profile for some device we can add a quirk to set a specific long_name for the device, Signed-off-by: Hans de Goede <hdegoede@redhat.com> --- sound/soc/intel/boards/bytcr_rt5651.c | 11 +++++++++++ 1 file changed, 11 insertions(+)
