Hi guys! I have an issue that's being pretty difficult to diagnose, since most of the howtos are mostly centered when the HDA sound card or specific codec is not detected correctly, but in my case, they are successfully initialized, and I can send audio, but nothing happens, not even errors, but no sound either, even after fiddling with every mixer setting too. I enabled the driver debug to be verbose cat /sys/module/snd/parameters/debug 2 and if I try to use the HDMI codec in the speaker test utility: speaker-test -c 2 -r 48000 -D plughw:0,3 the following is shown in the dmesg log: 36355.107191] ALSA sound/pci/hda/hda_intel.c:1894 azx_pcm_prepare: bufsize=0x10000, format=0x11 [36362.086043] ALSA sound/pci/hda/hda_codec.c:1473 hda_codec_cleanup_stream: NID=0x4 but when I use the analog codec (Sigmatel, works flawlessly): speaker-test -c 2 -r 48000 -D plughw:0,0 [36375.340599] ALSA sound/pci/hda/hda_intel.c:1894 azx_pcm_prepare: bufsize=0x10000, format=0x11 [36375.340615] ALSA sound/pci/hda/hda_codec.c:1410 hda_codec_setup_stream: NID=0x1e, stream=0x8, channel=0, format=0x11 [36375.353409] ALSA sound/pci/hda/hda_codec.c:1410 hda_codec_setup_stream: NID=0x1f, stream=0x8, channel=0, format=0x11 [36375.366758] ALSA sound/pci/hda/hda_codec.c:1410 hda_codec_setup_stream: NID=0x2, stream=0x8, channel=0, format=0x11 [36375.380057] ALSA sound/pci/hda/hda_codec.c:1410 hda_codec_setup_stream: NID=0x5, stream=0x8, channel=0, format=0x11 [36375.393383] ALSA sound/pci/hda/hda_codec.c:1410 hda_codec_setup_stream: NID=0x4, stream=0x8, channel=0, format=0x11 [36375.406719] ALSA sound/pci/hda/hda_codec.c:1410 hda_codec_setup_stream: NID=0x3, stream=0x8, channel=0, format=0x11 [36381.579249] ALSA sound/pci/hda/hda_codec.c:1473 hda_codec_cleanup_stream: NID=0x2 [36381.579256] ALSA sound/pci/hda/hda_codec.c:1473 hda_codec_cleanup_stream: NID=0x5 [36381.579261] ALSA sound/pci/hda/hda_codec.c:1473 hda_codec_cleanup_stream: NID=0x4 [36381.579265] ALSA sound/pci/hda/hda_codec.c:1473 hda_codec_cleanup_stream: NID=0x3 [36381.579270] ALSA sound/pci/hda/hda_codec.c:1473 hda_codec_cleanup_stream: NID=0x1e [36381.579274] ALSA sound/pci/hda/hda_codec.c:1473 hda_codec_cleanup_stream: NID=0x1f Clearly, no hda_codec_setup_stream invocation for the HDMI codec. I already followed this: http://www.alsa-project.org/main/index.php/Help_To_Debug_Intel_HDA and the HDA Analyzer shows the HDMI codec seemingly OK. Tried to ignore the HDMI device "handshake" with snd-hda-codec-hdmi.static_hdmi_pcm=1 but no luck either. My card is a Nvidia MCP77/78 HDMI, and I'm using Alsa driver/lib/util version 1.0.25. So I tried to even further see if the NVIDIA-specific codec setup routines are really being invoked, added my own "printk"s to the driver, and I see that the patch_nvhdmi_8ch_7x() function from the driver is indeed being invoked. Everything looks OK except for the missing hda_codec_setup_stream() when I try to use the HDMI codec (and the missing sound ;-) . Any ideas on how can I further debug this? TIA! -- Tomas J.
