ALSA: ctxfi: Fix silent playback on Titanium HD (SB1270)
Commit 4b490e0d103c ("ALSA: ctxfi: Add ADC helper functions for GPIO")
moved the GPIO_DATA read into hw_adc_stop(), but the Titanium HD
(SB1270) setup in hw_adc_init() uses the local data variable holding
the GPIO_CTRL value.
Writing this value to GPIO_DATA sets the output mute bits. Playback
runs without errors, but the outputs stay muted.
Re-read GPIO_DATA before setting the speed mode bits. Also, add the
delay after writing the mode bits, as in the original sequence.
On affected kernels, switching the output selection was reported to
restore clean playback.
