I responded to that one. I might collapse both ALSA patch that adds capture and mixer into one. Might make it lot easier and handle them at the same time. thanks, -- Shuah > >> >> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com> >> --- >> drivers/media/usb/au0828/au0828-core.c | 17 ++++++++++++++--- >> drivers/media/usb/au0828/au0828.h | 1 + >> 2 files changed, 15 insertions(+), 3 deletions(-) >> >> diff --git a/drivers/media/usb/au0828/au0828-core.c b/drivers/media/usb/au0828/au0828-core.c >> index 722e073..886fb28 100644 >> --- a/drivers/media/usb/au0828/au0828-core.c >> +++ b/drivers/media/usb/au0828/au0828-core.c >> @@ -264,6 +264,7 @@ static int au0828_create_media_graph(struct au0828_dev *dev) >> struct media_entity *entity; >> struct media_entity *tuner = NULL, *decoder = NULL; >> struct media_entity *audio_capture = NULL; >> + struct media_entity *mixer = NULL; >> int i, ret; >> >> if (!mdev) >> @@ -284,6 +285,9 @@ static int au0828_create_media_graph(struct au0828_dev *dev) >> case MEDIA_ENT_F_AUDIO_CAPTURE: >> audio_capture = entity; >> break; >> + case MEDIA_ENT_F_AUDIO_MIXER: >> + mixer = entity; >> + break; >> } >> } >> >> @@ -356,14 +360,21 @@ static int au0828_create_media_graph(struct au0828_dev *dev) >> } >> } >> } >> - if (audio_capture && !dev->audio_capture_linked) { >> - ret = media_create_pad_link(decoder, AU8522_PAD_AUDIO_OUT, >> - audio_capture, 0, >> + if (mixer && audio_capture && !dev->audio_capture_linked) { >> + ret = media_create_pad_link(mixer, 1, audio_capture, 0, >> MEDIA_LNK_FL_ENABLED); >> if (ret) >> return ret; >> dev->audio_capture_linked = 1; >> } >> + if (mixer && !dev->mixer_linked) { >> + ret = media_create_pad_link(decoder, AU8522_PAD_AUDIO_OUT, >> + mixer, 0, >> + MEDIA_LNK_FL_ENABLED); >> + if (ret) >> + return ret; >> + dev->mixer_linked = 1; >> + } >> #endif >> return 0; >> } >> diff --git a/drivers/media/usb/au0828/au0828.h b/drivers/media/usb/au0828/au0828.h >> index 3707664..b9aa74f 100644 >> --- a/drivers/media/usb/au0828/au0828.h >> +++ b/drivers/media/usb/au0828/au0828.h >> @@ -289,6 +289,7 @@ struct au0828_dev { >> bool vdev_linked; >> bool vbi_linked; >> bool audio_capture_linked; >> + bool mixer_linked; >> struct media_link *active_link; >> struct media_entity *active_link_owner; >> #endif
