https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218132 --- Comment #3 from Sean Bruno <sbruno@FreeBSD.org> --- It appears that we may need to support seperate capture/playback streams, perhaps. Linux seems to use a different tag assignment process based on the flag=20 hda_controller.h:#define AZX_DCAPS_SEPARATE_STREAM_TAG (1 << 30) /* capture and playback use separate stream tag */ This seems to use two different identifiers in a 2 element array instead of= a single integer. hda_controller.c::azx_init_streams(): /* initialize SD streams */ int azx_init_streams(struct azx *chip) { int i; int stream_tags[2] =3D { 0, 0 }; /* initialize each stream (aka device) * assign the starting bdl address to each stream (device) * and initialize */ for (i =3D 0; i < chip->num_streams; i++) { struct azx_dev *azx_dev =3D kzalloc(sizeof(*azx_dev), GFP_KERNEL);=20 int dir, tag; if (!azx_dev) return -ENOMEM; dir =3D stream_direction(chip, i); /* stream tag must be unique throughout * the stream direction group, * valid values 1...15 * use separate stream tag if the flag * AZX_DCAPS_SEPARATE_STREAM_TAG is used */ if (chip->driver_caps & AZX_DCAPS_SEPARATE_STREAM_TAG) tag =3D ++stream_tags[dir]; else tag =3D i + 1; snd_hdac_stream_init(azx_bus(chip), azx_stream(azx_dev), i, dir, tag); } return 0; } --=20 You are receiving this mail because: You are the assignee for the bug.=
