Re: [alsa-devel] Tegra driver silent running on linux-next

I've made the Tegra audio driver compile against ALSA's -next, and it seems like it's working; the files in /sys/kernel/debug/asoc contain everything I'd expect, aplay -[lL] list what I'd expect, aplay runs without errors and completes after the expected about of time, same for speaker-test.

However, the headphones are completely silent.

Bah, it's working now. Tegra wasn't driving anything on the codec's MCLK input. I thought I'd checked all the Tegra clock programming, but obviously not well enough...

(and for reference, the DAPM/routing calls I added weren't actually required)

Sorry for the noise.
