Each hw module node is named after the corresponding hw module library base name. 17# For instance, "primary" corresponds to audio.primary.<device>.so. 18# The "primary" module is mandatory and must include at least one output with 19# AUDIO_OUTPUT_FLAG_PRIMARY flag. 20# Each module descriptor contains one or more output profile descriptors and zero or more 21# input profile descriptors. Each profile lists all the parameters supported by a given output 22# or input stream category. 23# The "channel_masks", "formats", "devices" and "flags" are specified using strings corresponding 24# to enums in audio.h and audio_policy.h. They are concatenated by use of "|" without space or "\n". 25#device sr changed from 44100 to 48000 to adapt chip 26audio_hw_modules { 27 primary { 28 outputs { 29 primary { 30 sampling_rates 48000 31 channel_masks AUDIO_CHANNEL_OUT_STEREO 32 formats AUDIO_FORMAT_PCM_16_BIT 33 devices AUDIO_DEVICE_OUT_SPEAKER|AUDIO_DEVICE_OUT_HDMI 34 flags AUDIO_OUTPUT_FLAG_PRIMARY 35 } 36 hw_av_sync { 37 sampling_rates 8000|11025|16000|22050|24000|32000|44100|48000 38 channel_masks AUDIO_CHANNEL_OUT_MONO|AUDIO_CHANNEL_OUT_STEREO 39 formats AUDIO_FORMAT_PCM_16_BIT 40 devices AUDIO_DEVICE_OUT_SPEAKER|AUDIO_DEVICE_OUT_HDMI 41 flags AUDIO_OUTPUT_FLAG_DIRECT|AUDIO_OUTPUT_FLAG_HW_AV_SYNC 42 } 43 hw_compress { 44 sampling_rates 8000|11025|16000|22050|24000|32000|44100|48000 45 channel_masks AUDIO_CHANNEL_OUT_STEREO|AUDIO_CHANNEL_OUT_MONO|AUDIO_CHANNEL_OUT_5POINT1|AUDIO_CHANNEL_OUT_7POINT1 46 formats AUDIO_FORMAT_AC3|AUDIO_FORMAT_E_AC3 47 devices AUDIO_DEVICE_OUT_SPEAKER|AUDIO_DEVICE_OUT_HDMI 48 flags AUDIO_OUTPUT_FLAG_DIRECT 49 } 50 hw_av_sync_compress { 51 sampling_rates 8000|11025|16000|22050|24000|32000|44100|48000 52 channel_masks AUDIO_CHANNEL_OUT_STEREO|AUDIO_CHANNEL_OUT_MONO|AUDIO_CHANNEL_OUT_5POINT1|AUDIO_CHANNEL_OUT_7POINT1 53 formats AUDIO_FORMAT_AC3|AUDIO_FORMAT_E_AC3 54 devices AUDIO_DEVICE_OUT_SPEAKER|AUDIO_DEVICE_OUT_HDMI 55 flags AUDIO_OUTPUT_FLAG_DIRECT|AUDIO_OUTPUT_FLAG_HW_AV_SYNC 56 } 57 } 58 inputs { 59 primary { 60 sampling_rates 8000|11025|16000|22050|24000|32000|44100|48000 61 channel_masks AUDIO_CHANNEL_IN_MONO 62 formats AUDIO_FORMAT_PCM_16_BIT 63 devices AUDIO_DEVICE_IN_BUILTIN_MIC 64 } 65 } 66 } 67 a2dp { 68 outputs { 69 a2dp { 70 sampling_rates 44100|48000 71 channel_masks AUDIO_CHANNEL_OUT_STEREO 72 formats AUDIO_FORMAT_PCM_16_BIT 73 devices AUDIO_DEVICE_OUT_ALL_A2DP 74 } 75 } 76 input { 77 a2dp { 78 sampling_rates 44100|48000 79 channel_masks AUDIO_CHANNEL_IN_STEREO|AUDIO_CHANNEL_IN_MONO 80 formats AUDIO_FORMAT_PCM_16_BIT|AUDIO_FORMAT_PCM_8_BIT 81 devices AUDIO_DEVICE_IN_BLUETOOTH_A2DP 82 } 83 } 84 } 85 usb { 86 outputs { 87 usb_device { 88 sampling_rates dynamic 89 channel_masks dynamic 90 formats dynamic 91 devices AUDIO_DEVICE_OUT_USB_DEVICE 92 } 93 } 94 inputs { 95 usb_device { 96 sampling_rates dynamic 97 channel_masks dynamic 98 formats dynamic 99 devices AUDIO_DEVICE_IN_USB_DEVICE 100 } 101 } 102 } 103 r_submix { 104 outputs { 105 submix { 106 sampling_rates 48000 107 channel_masks AUDIO_CHANNEL_OUT_STEREO 108 formats AUDIO_FORMAT_PCM_16_BIT 109 devices AUDIO_DEVICE_OUT_REMOTE_SUBMIX 110 } 111 } 112 inputs { 113 submix { 114 sampling_rates 8000|48000 115 channel_masks AUDIO_CHANNEL_IN_MONO|AUDIO_CHANNEL_IN_STEREO 116 formats AUDIO_FORMAT_PCM_16_BIT 117 devices AUDIO_DEVICE_IN_REMOTE_SUBMIX 118 } 119 } 120 } 121} 122
