Yes. Considering that we have Woofers and Tweeters speakers consistencies.

Yes, you are right. The purpose to do is Woofers as default and Tweeters+Woofers as specific project. I revised them below. Or any advices?

True. My mistake, just remain one(apart from rt1011_rt5682_map).

Yes. Remove tweeters from rt1011_rt5682_map.

Thanks for addressing. I revised the if/else logic below
		if (sof_rt1011_quirk & (SOF_RT1011_SPEAKER_WL |
					SOF_RT1011_SPEAKER_WR)) {
			/* TDM slots for WL/WR */
			....
		}
		if (sof_rt1011_quirk & (SOF_RT1011_SPEAKER_TL |
					SOF_RT1011_SPEAKER_TR)) {
			/* TDM slots for TL/TR */
			...
		}

Yes, I will add the check conditions separately. Afterwards I will revise and submit the entirely new one.
