Hi,
the Thinkpad Tablet 10 has an impressive amount of problems under Linux, among which the audio is completely broken.
The kernel log is: [ 7.532413] rt5640 i2c-10EC5640:00: Device with ID register 6271 is not rt5640/39 [ 7.908208] byt-rt5640 byt-rt5640: ASoC: CPU DAI baytrail-pcm-audio not registered [ 7.908231] platform byt-rt5640: Driver byt-rt5640 requests probe deferral [ 7.931549] baytrail-pcm-audio baytrail-pcm-audio: error: invalid DMA engine 0 [ 7.931557] baytrail-pcm-audio baytrail-pcm-audio: sst_dma_new failed -22 [ 7.967040] baytrail-pcm-audio baytrail-pcm-audio: FW version: 04.05.13.a0 [ 7.967047] baytrail-pcm-audio baytrail-pcm-audio: Build type: a0 [ 7.967051] baytrail-pcm-audio baytrail-pcm-audio: Build date: Apr 2 2014 14:14:39 [ 7.967212] byt-rt5640 byt-rt5640: ASoC: CODEC DAI rt5640-aif1 not registered [ 7.967248] platform byt-rt5640: Driver byt-rt5640 requests probe deferral
I'm running kernel 3.19 with the latest firmware from the linux-firmware repository.
