6 | |||
7 | STATE OF DEVELOPMENT: | ||
8 | |||
9 | This driver is being developed on the initiative of Piotr Makowski (oponek@gmail.com) and financed by Lars Bergmann. | ||
10 | Development is carried out by Rainer Zimmermann (mail@lightshed.de). | ||
11 | |||
12 | ESI provided a sample Maya44 card for the development work. | ||
13 | |||
14 | However, unfortunately it has turned out difficult to get detailed programming information, so I (Rainer Zimmermann) had to find out some card-specific information by experiment and conjecture. Some information (in particular, several GPIO bits) is still missing. | ||
15 | |||
16 | This is the first testing version of the Maya44 driver released to the alsa-devel mailing list (Feb 5, 2008). | ||
17 | |||
18 | |||
19 | The following functions work, as tested by Rainer Zimmermann and Piotr Makowski: | ||
20 | |||
21 | - playback and capture at all sampling rates | ||
22 | - input/output level | ||
23 | - crossmixing | ||
24 | - line/mic switch | ||
25 | - phantom power switch | ||
26 | - analogue monitor a.k.a bypass | ||
27 | |||
28 | |||
29 | The following functions *should* work, but are not fully tested: | ||
30 | |||
31 | - Channel 3+4 analogue - S/PDIF input switching | ||
32 | - S/PDIF output | ||
33 | - all inputs/outputs on the M/IO/DIO extension card | ||
34 | - internal/external clock selection | ||
35 | |||
36 | |||
37 | *In particular, we would appreciate testing of these functions by anyone who has access to an M/IO/DIO extension card.* | ||
38 | |||
39 | |||
40 | Things that do not seem to work: | ||
41 | |||
42 | - The level meters ("multi track") in 'alsamixer' do not seem to react to signals in (if this is a bug, it would probably be in the existing ICE1724 code). | ||
43 | |||
44 | - Ardour 2.1 seems to work only via JACK, not using ALSA directly or via OSS. This still needs to be tracked down. | ||
45 | |||
46 | |||
47 | DRIVER DETAILS: | ||
48 | |||
49 | the following files were added: | ||
50 | |||
51 | pci/ice1724/maya44.c - Maya44 specific code | ||
52 | pci/ice1724/maya44.h | ||

55 | i2c/other/wm8776.c - low-level access routines for Wolfson WM8776 codecs | ||
56 | include/wm8776.h | ||
57 | |||
58 | |||
59 | Note that the wm8776.c code is meant to be card-independent and does not actually register the codec with the ALSA infrastructure. | ||
60 | This is done in maya44.c, mainly because some of the WM8776 controls are used in Maya44-specific ways, and should be named appropriately. | ||
61 | |||
62 | |||
63 | the following files were created in pci/ice1724, simply #including the corresponding file from the alsa-kernel tree: | ||

75 | envy24ht.h | ||
76 | se.h | ||
77 | prodigy_hifi.h | ||
78 | |||
79 | |||
80 | *I hope this is the correct way to do things.* | ||
81 | |||
82 | |||
83 | SAMPLING RATES: | ||
84 | |||
85 | The Maya44 card (or more exactly, the Wolfson WM8776 codecs) allow a maximum sampling rate of 192 kHz for playback and 92 kHz for capture. | ||
86 | |||
87 | As the ICE1724 chip only allows one global sampling rate, this is handled as follows: | ||
88 | |||
89 | * setting the sampling rate on any open PCM device on the maya44 card will always set the *global* sampling rate for all playback and capture channels. | ||
90 | |||
91 | * In the current state of the driver, setting rates of up to 192 kHz is permitted even for capture devices. | ||
92 | |||
93 | *AVOID CAPTURING AT RATES ABOVE 96kHz*, even though it may appear to work. The codec cannot actually capture at such rates, meaning poor quality. | ||
94 | |||
95 | |||
96 | I propose some additional code for limiting the sampling rate when setting on a capture pcm device. However because of the global sampling rate, this logic would be somewhat problematic. | ||
97 | |||
98 | The proposed code (currently deactivated) is in ice1712.h.patch, ice1724.c and maya44.c (in pci/ice1712). | ||
99 | |||
100 | |||
101 | SOUND DEVICES: | ||
102 | |||
103 | PCM devices correspond to inputs/outputs as follows (assuming Maya44 is card #0): | ||
104 | |||
105 | hw:0,0 input - stereo, analog input 1+2 | ||
106 | hw:0,0 output - stereo, analog output 1+2 | ||
107 | hw:0,1 input - stereo, analog input 3+4 OR S/PDIF input | ||
108 | hw:0,1 output - stereo, analog output 3+4 (and SPDIF out) | ||
109 | |||
110 | |||
111 | NAMING OF MIXER CONTROLS: | ||
112 | |||
113 | (for more information about the signal flow, please refer to the block diagram on p.24 of the ESI Maya44 manual, or in the ESI windows software). | ||
114 | |||
115 | |||
116 | PCM: (digital) output level for channel 1+2 | ||
117 | PCM 1: same for channel 3+4 | ||
118 | |||
119 | Mic Phantom+48V: switch for +48V phantom power for electrostatic microphones on input 1/2. | ||
120 | Make sure this is not turned on while any other source is connected to input 1/2. | ||
121 | It might damage the source and/or the maya44 card. | ||
122 | |||
123 | Mic/Line input: if switch is is on, input jack 1/2 is microphone input (mono), otherwise line input (stereo). | ||
124 | |||
125 | Bypass: analogue bypass from ADC input to output for channel 1+2. Same as "Monitor" in the windows driver. | ||
126 | Bypass 1: same for channel 3+4. | ||
127 | |||
128 | Crossmix: cross-mixer from channels 1+2 to channels 3+4 | ||
129 | Crossmix 1: cross-mixer from channels 3+4 to channels 1+2 | ||
130 | |||
131 | IEC958 Output: switch for S/PDIF output. | ||
132 | This is not supported by the ESI windows driver. | ||
133 | S/PDIF should output the same signal as channel 3+4. [untested!] | ||
134 | |||
135 | |||
136 | Digitial output selectors: | ||
137 | |||
138 | These switches allow a direct digital routing from the ADCs to the DACs. | ||
139 | Each switch determines where the digital input data to one of the DACs comes from. | ||
140 | They are not supported by the ESI windows driver. | ||
141 | For normal operation, they should all be set to "PCM out". | ||
142 | |||
143 | H/W: Output source channel 1 | ||
144 | H/W 1: Output source channel 2 | ||
145 | H/W 2: Output source channel 3 | ||
146 | H/W 3: Output source channel 4 | ||
147 | |||
148 | H/W 4 ... H/W 9: unknown function, left in to enable testing. | ||
149 | Possibly some of these control S/PDIF output(s). | ||
150 | If these turn out to be unused, they will go away in later driver versions. | ||
151 | |||
152 | Selectable values for each of the digital output selectors are: | ||
153 | "PCM out" -> DAC output of the corresponding channel (default setting) | ||
154 | "Input 1"... | ||
155 | "Input 4" -> direct routing from ADC output of the selected input channel | ||
156 | |||
