One thing you can try is to add a delay in the codec communicationcode. Try the patch below, for example. thanks, Takashi diff --git a/sound/pci/hda/patch_ca0110.c b/sound/pci/hda/patch_ca0110.cindex adc8387..4e0c1f4 100644--- a/sound/pci/hda/patch_ca0110.c+++ b/sound/pci/hda/patch_ca0110.c@@ -502,6 +502,8 @@ int patch_ca0110(struct hda_codec *codec) return -ENOMEM; codec->spec = spec; + codec->bus->needs_damn_long_delay = 1;+ err = ca0110_parse_auto_config(codec); if (err < 0) goto error; -------------------------------------------------------------------------This SF.Net email is sponsored by the Moblin Your Move Developer's challengeBuild the coolest Linux based applications with Moblin SDK & win great prizesGrand prize is a trip for two to an Open Source event anywhere in the worldhttp://moblin-contest.org/redirect.php?banner_id=100&url=/_______________________________________________Alsa-user mailing listAlsa-user@xxxxxxxxxxxxxxxxxxxxxxxxxx://lists.sourceforge.net/lists/listinfo/alsa-user
