ALSA: bebob: fix to detect configured source of sampling clock for Focusrite Saffire Pro i/o series

2019-11-12T18:26:52+00:00

commit 706ad6746a66546daf96d4e4a95e46faf6cf689a upstream. For Focusrite Saffire Pro i/o, the lowest 8 bits of register represents configured source of sampling clock. The next lowest 8 bits represents whether the configured source is actually detected or not just after the register is changed for the source. Current implementation evaluates whole the register to detect configured source. This results in failure due to the next lowest 8 bits when the source is connected in advance. This commit fixes the bug.

ALSA: bebob: Fix prototype of helper function to return negative value

2019-11-06T12:08:55+00:00

commit f2bbdbcb075f3977a53da3bdcb7cd460bc8ae5f2 upstream. A helper function of ALSA bebob driver returns negative value in a function which has a prototype to return unsigned value. This commit fixes it by changing the prototype.

ALSA: bebob: fix wrong reference count for stream functionality at error path of rawmidi interface

2019-07-07T09:19:55+00:00

In IEC 61883-6, several types of sampling data can be multiplexed into payload of common isochronous packet (CIP). For typical audio and music units, PCM samples and MIDI messages are multiplexed into one packet streaming. ALSA bebob driver allows applications of rawmidi interface to start packet streaming for transmission of MIDI messages. However at error path, the reference count of stream functionality is not operated correctly. This can brings a bug that packet streaming is not stopped when all referrers release the count. This commit fixes the bug. Fixes: ac2888b958f2 ("ALSA: bebob: configure sampling transfer frequency in pcm.hw_params callback") Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: bebob: ensure to release isochronous resources in pcm.hw_params callback

2019-06-21T09:47:09+00:00

When stopping packet streaming in reserve function for duplex streams, isochronous resources should be released. Fixes: 7bc93821a70a ("ALSA: firewire-lib: split allocation of isochronous resources from establishment of connection") Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire-lib: split allocation of isochronous resources from establishment of connection

2019-06-17T06:18:36+00:00

In current implementation, establishment connection corresponds to allocation of isochronous resources. Although this is an ideal implementation of CMP described in IEC 61883-1, it's not enough efficient to recover PCM substream multiplexed in packet streaming. The packet streaming can always restart on the same allocated isochronous resources even if the previous packet streaming corrupted. This commit splits allocation of isochronous resources from establishment of connection so that CMP runs with allocated isochronous resources.
