Says the (max98090, rt5640). ---- As the chromeos reported issue:(https://chromium.googlesource.com/chromiumos/third_party/kernel/+/v3.14) For detail: In that bug we want to add 32000 to sound/soc/rockchip/rockchip_max98090.c rk_aif1_hw_params. However that does not work. Previously, in https://chromium-review.googlesource.com/#/c/268398/ , rate 8000, 1600, 96000 were added. However, those rates do not work. I got the same audio as 48000 when I run aplay -D hw:0,0 /usr/local/autotest/cros/audio/fix_440_16_half.raw --rate 8000 -f S16_LE -c2 aplay -D hw:0,0 /usr/local/autotest/cros/audio/fix_440_16_half.raw --rate 16000 -f S16_LE -c2 aplay -D hw:0,0 /usr/local/autotest/cros/audio/fix_440_16_half.raw --rate 96000 -f S16_LE -c2 They all sound identical to aplay -D hw:0,0 /usr/local/autotest/cros/audio/fix_440_16_half.raw --rate 48000 -f S16_LE -c2 Also, recording using aplay -D hw:0,0 /usr/local/test.raw --rate 96000 -f S16_LE -c2 and examine the output we see it was recording using 48000. Okay, let's add this series patchs to fix this issue. arecord -D hw:0 -f S16_LE -c 2 --rate 96000 -d 5 foobar.wav and aplay -D hw:0 foobar.wav Tested on veyron devices. Changes in v1: - change the subject and commit. - remove the print message dev_dbg(). - Fix a subject missspell.
