Hi there, I've been experiencing an issue with static noise through headphones with a Realtek ALC3246 chip on a Skylake laptop. The white noise is present the entire time the headphones are plugged in, but does disappear when either of the following is done through alsamixer: 1. switch capture to Headphone Mic 2. increase Headphone Mic Boost one level (the next two levels produce more static noise); the Headphone Mic does not need to be selected for capture
I'm running the Linux 4.4-rc4 kernel image from the Intel graphics folks: https://01.org/linuxgraphics/. In particular, the current image is built from the drm-nightly branch, with the latest sound commit being: 55913110dde2d -- ALSA: hda - Allow i915 binding later in codec driver. I've experienced the same issue with 4.3 and prior releases of the 4.4 kernel. Please let me know if this is better suited for linux-sound (although that mailing seemed very low traffic) or if this doesn't seem like a driver issue. -- Cheers, Timur -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
