The verbs above are "4-Bit verbs", which are correctly shifted in order to assemble 40-Bit commands in hda_intel.c:azx_corb_send_cmd() Now azx_corb_send_cmd() seems to use an on-chip command buffer. I'm going to try to use azx_single_send_cmd() instead tonight (module parameter single_cmd=1), to see whether this makes any difference. -- Best regards, Dag Lem _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
