Hi, The issue seems related to mismatched offsets in the patching process, likely due to differences between your snapshot and the intended source files. Try ensuring your alsa-kernel source matches the version expected by the snapshot. Alternatively, check for recent updates or fixes in the ALSA mailing lists. If the issue persists, you may need to manually adjust the failed hunks in pcm_native.c.rej. http://therutificador.cl/
