Hello, as hibernation (swsusp) started to work with my CPU, I found that my Turtle Beach Malibu stops working after resume from hibernation. It's caused by fact that the card is not enabled on the pnp layer during resume - and thus card registers are inaccessible (reads return FFs, writes go nowhere). During resume, pnp_bus_resume() in drivers/pnp/driver.c is called for each pnp device. This function calls pnp_start_dev() only when the PNP_DRIVER_RES_DO_NOT_CHANGE bit is NOT seting pnp_drv->flags. But the cs4236 driver in sound/isa/cs423x/cs4236.c explicitly sets the .flags to PNP_DRIVER_RES_DISABLE - it's value is 3 and that includes PNP_DRIVER_RES_DO_NOT_CHANGE bit. The same .flags value is present in many of the ALSA ISA sound drivers. Removing that .flags line caused this to appear inlog when loading snd_cs4236 module: CS4236+ WSS PnP manual resources are invalid, using auto config CS4236+ CTRL PnP manual resources are invalid, using auto config CS4236+ MPU401 PnP manual resources are invalid, using auto config and the sound now works after resume! So the question is: why is this line present? Is this a bug? What's the correct fix? -- Ondrej Zary _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
