ALSA: bebob: Fix failure to detect source of clock for Terratec Phase 88

2014-10-10T15:25:30+00:00

This patch fixes a failure to open PCM device with -ENOSYS in
Terratec Phase 88.

Terratec Phase 88 has two Selector Function Blocks of AVC Audio subunit
to switch source of clock. One is to switch internal/external for the
source and another is to switch word/spdif for the external clock.

The IDs for these Selector Function Blocks are 9 and 8. But in current
implementation they're 0 and 0.

ALSA: firewire-lib/dice: add arrangements of PCM pointer and interrupts for Dice quirk

2014-08-29T07:52:07+00:00

In IEC 61883-6, one data block transfers one event. In ALSA, the event equals one PCM frame,
hence one data block transfers one PCM frame. But Dice has a quirk at higher sampling rate
(176.4/192.0 kHz) that one data block transfers two PCM frames.

Commit 10550bea44a8 ("ALSA: dice/firewire-lib: Keep dualwire mode but obsolete
CIP_HI_DUALWIRE") moved some codes related to this quirk into Dice driver. But the commit
forgot to add arrangements for PCM period interrupts and DMA pointer updates. As a result, Dice
driver cannot work correctly at higher sampling rate.

This commit adds 'double_pcm_frames' parameter to amdtp structure for this quirk. When this
parameter is set, PCM period interrupts and DMA pointer updates occur at double speed than in
IEC 61883-6.

ALSA: dice: fix wrong channel mappping at higher sampling rate

2014-08-29T07:51:45+00:00

The channel mapping is initialized by amdtp_stream_set_parameters(), however
Dice driver set it before calling this function. Furthermore, the setting is
wrong because the index is the value of array, and vice versa.

This commit moves codes for channel mapping after the function and set it correctly.

ALSA: bebob: Correction for return value of special_clk_ctl_put() in error

2014-07-22T15:31:28+00:00

This commit is a supplement to my previous patch.
http://mailman.alsa-project.org/pipermail/alsa-devel/2014-July/079190.html

The special_clk_ctl_put() still returns 0 in error handling case. It should
return -EINVAL.

ALSA: bebob: Correction for return value of .put callback

2014-07-22T14:21:54+00:00

This commit is for correction of my misunderstanding about return value of
.put callback in ALSA Control interface.

According to 'Writing ALSA Driver' (*1), return value of the callback has
three patterns; 1: changed, 0: not changed, an negative value: fatal error.

But I misunderstood that it's boolean; zero or nonzero.

ALSA: bebob: Use different labels for digital input/output

2014-07-22T14:21:30+00:00

This commit uses different labels for control elements of digital input/output
interfaces to correct my misunderstanding about M-Audio Firewire 1814 and
ProjectMix I/O.

According to user manuals for these two models, they have two modes for
digital input; one is S/PDIF in both of optical and coaxial interfaces,
another is ADAT in optical interface only.

But in current implementation, a control element for it reduced labels which
a control element for digital output uses because of my misunderstanding
that optical interface is not available for digital input with S/PDIF mode.
