First of all, you're right about 2 SADs for PCM. The weird thing is that 192kHz support... According to the EDID (SADs) it should be supported: Format: 1 (PCM) Channels:1 Freq:0x7F (32-192) B2:0x07 (16-24b) Format: 1 (PCM) Channels:7 Freq:0x7F (32-192) B2:0x07 (16-24b) Format: 2 (AC3) Channels:7 Freq:0x07 (32-48) B2:0x50 (640?) Format: 7 (DTS) Channels:7 Freq:0x06 (44-48) B2:0xC0 (1536?) Format: 10 (EAC3) Channels:7 Freq:0x06 (44-48) B2:0x00 Format: 11 (DTS_HD) Channels:7 Freq:0x7E (44-192) B2:0x01 Format: 12 (MLP) Channels:7 Freq:0x1E (44-96) B2:0x00 So I performed more tests and: 1) speaker-test -D hdmi:CARD=Generic,DEV=0 -c6 -r192000 -F S16_LE A nice noise for rear right and rear left, silent for the rest 2) speaker-test -D hdmi:CARD=Generic,DEV=0 -c6 -r176400 -F S16_LE A nice noise for rear right and rear left, short "bump" sound for the rest 3) speaker-test -D hdmi:CARD=Generic,DEV=0 -c6 -r96000 -F S16_LE A nice noise for all speakers (the same applies to 88200, 48000, 44100, 32000) I don't get it. Onkyo reports support for 192kHz and it supports it, but only for 2 rear speakers... does it make any sense do you? -- Rafał -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
