Ah ok so you want the audio to stop during suspend?
Ok in that case can we get a bit more of log, your log finished up here:
[ 72.308238] arizona spi1.0: Suspend, disabling IRQ [ 72.320286] arizona spi1.0: 400 <= 0 [ 72.320310] s3c64xx_spi_runtime_resume [ 72.336047] arizona spi1.0: 51a <= 0 [ 72.336217] arizona spi1.0: 101 <= 8604 [ 72.336401] arizona spi1.0: 171 <= 3 [ 72.336425] arizona spi1.0: 171 <= 2 [ 72.336731] arizona spi1.0: 171 <= 0 [ 72.336751] arizona spi1.0: SYSCLK cleared [ 72.338584] arizona spi1.0: SYSCLK cleared [ 72.339123] s3c64xx_spi_suspend [ 72.355866] arizona spi1.0: Late suspend, reenabling IRQ [ 72.355893] >>> noirq failed because of spi1 [ 72.355948] arizona spi1.0: Early resume, disabling IRQ [ 72.416798] PM: noirq suspend of devices failed
Which finished too early as we can't see which IRQ it was that triggered the wakeup.
Thanks, Charles
