Maybe derailed was a little harsh. I was appreciative of your answer either way, as I might have left out some necessary information to make you ask about those things. This is still very low level as far as I understand it, so I'm not completely sure how to ask about what I'm wondering :) > > To start please run the following command and let's see what ALSA tells us: > > cat /proc/asound/card*/eld#0.* There was 16 of these entries, /proc/asound/card1/eld#0.4 was my Acer monitor which I managed to get sound through with my command: aplay -D plughw:1,7 sample.wav Most of the others simply showed: monitor_present 0 eld_valid 0 The connected TV was here: # cat /proc/asound/card1/eld#0.0 monitor_present 1 eld_valid 1 monitor_name TOSHIBA-TV connection_type HDMI eld_version [0x2] CEA-861D or below edid_version [0x3] CEA-861-B, C or D manufacture_id 0x6252 product_id 0x108 port_id 0x400 support_hdcp 0 support_ai 0 audio_sync_delay 62 speakers [0xffff] FL/FR LFE FC RL/RR RC FLC/FRC RLC/RRC FLW/FRW FLH/FRH TC FCH sad_count 2 sad0_coding_type [0x1] LPCM sad0_channels 2 sad0_rates [0xe0] 32000 44100 48000 sad0_bits [0xe0000] 16 20 24 sad1_coding_type [0x2] AC-3 sad1_channels 6 sad1_rates [0xe0] 32000 44100 48000 sad1_max_bitrate 640000 All of this is quite cryptic to me, so if you can glean any useful information from it that would be great. The monitor output is fairly similar if you exclude the sad1*-lines at the end, the most prominent difference being the speakers line, which only listed '[0x1] FL/FR' Regards, Arve
