[alsa-devel] [PATCH 0/5] assorted HDMI cleanups
by Wu Fengguang 19 Nov '08

19 Nov '08

Hi Takashi, Here are 5 HDMI cleanup patches, some renames the code and others renames the user visible output messages. The new output goes like: dmesg [ 5742.169578] detected monitor <9d><80>t connection type Display Port [ 5742.169580] available speakers: FL/FR LFE FLC/FRC [ 5742.169582] supports coding type MLP (Dolby TrueHD): channels = 7, rates = 48000 176400 [ 5742.169585] supports coding type AC-3: channels = 1, rates = 48000 88200 192000, max bitrate = 1208000 [ 5742.169588] supports coding type AC-3: channels = 2, rates = 48000 384000, max bitrate = 960000 [ 5742.169591] supports coding type ATRAC: channels = 5, rates = 48000 88200 384000, max bitrate = 224000 /proc/asound/card0/eld\#3 monitor name �� connection_type Display Port eld_version [0xb] reserved edid_version [0x3] CEA-861-B, C or D manufacture_id 0xee5a product_id 0x923c port_id 0x18b263a03e17d1b5 support_hdcp 1 support_ai 1 audio_sync_delay 216 speakers [0x23] FL/FR LFE FLC/FRC sad_count 4 sad0_coding_type [0xc] MLP (Dolby TrueHD) sad0_channels 7 sad0_rates [0x240] 48000 176400 sad1_coding_type [0x2] AC-3 sad1_channels 1 sad1_rates [0x4c0] 48000 88200 192000 sad1_max_bitrate 1208000 sad2_coding_type [0x2] AC-3 sad2_channels 2 sad2_rates [0x1840] 48000 384000 sad2_max_bitrate 960000 sad3_coding_type [0x8] ATRAC sad3_channels 5 sad3_rates [0x8c0] 48000 88200 384000 sad3_max_bitrate 224000 Thanks, Fengguang --

[alsa-devel] Listing up to 8 PCM devices
by Gregoire ETIENNE 19 Nov '08

19 Nov '08

Hi, I'm currently writting a driver with up to 8 pcm devices, so I turned on "Dynamic device file minor numbers" option. But when I try to list devices through aplay or a record (which are calling ioctl with cmd SNDRV_CTL_IOCTL_PCM_NEXT_DEVICE) I can only list devices from 0 to 7. This is due to this code : linux/sound/core/pcm.c l.64 ------------------------------ case SNDRV_CTL_IOCTL_PCM_NEXT_DEVICE: { int device; if (get_user(device, (int __user *)arg)) return -EFAULT; mutex_lock(&register_mutex); device = device < 0 ? 0 : device + 1; while (device < SNDRV_PCM_DEVICES) { if (snd_pcm_search(card, device)) break; device++; } if (device == SNDRV_PCM_DEVICES) device = -1; mutex_unlock(&register_mutex); if (put_user(device, (int __user *)arg)) return -EFAULT; return 0; } ------------------------------ because SNDRV_PCM_DEVICES is defined to 8 and do not change even if I selected "Dynamic device file minor numbers" option. Is there anything I missed ?

Yes. Obviously the ELD stuct has not been populated yet. Thanks, Fengguang

[alsa-devel] [PATCH 0/4] multi-channel HDMI audio support
by Wu Fengguang 19 Nov '08

19 Nov '08

Hi Takashi, This patchset attempts to support multi-channel HDMI audio. It contains two basic operations: - setup the CA(channel-allocation) byte in the audio infoframe - setup the converter channel to HDMI slot mapping Please read patch 3 for more detailed descriptions: [PATCH 1/4] hda: make standalone hdmi_fill_audio_infoframe() [PATCH 2/4] hda: make global snd_print_channel_allocation() [PATCH 3/4] hda: HDMI channel allocations for audio infoframe [PATCH 4/4] hda: HDMI channel mapping cleanups The current implementation only does minimal works that ensure multi-channel audio playing out. However the wrong speakers may be selected. We could elaborate the framework/policy if it proves to be a problem. Thank you, Fengguang --

[alsa-devel] HDA-emu v0.0.3
by Takashi Iwai 18 Nov '08

18 Nov '08

Hi, right now I updated hda-emu to version 0.0.3. hda-emu is a HD-audio emulation program that is hopefully useful for testing and debugging HD-audio drivers. This version contains a simple PCM test in addition to handling of control elements. The latest package is found at ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-emu-0.0.3.tar.gz The git tree is git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-emu.git Any fixes, improvements and feedbacks are appreciated thanks, Takashi
