[alsa-devel] Only stereo output possible with ATI Tahiti XT HDMI Audio [Radeon HD 7970 Series] [1002:aaa0]
by Olivier Langlois 16 May '13

16 May '13

I have an HDMI chain with a Radeon card on 1 side and a 1080P monitor at the other end with a Pioner SC-09TX A/V Receiver in the middle. Video is transmitted fine. 2 channels pcm plays fine on the receiver. I am totally unable to output sound with 8 channels. lano1106@whippet2 /proc/asound/card0 $ speaker-test -c8 speaker-test 1.0.27 Playback device is default Stream parameters are 48000Hz, S16_LE, 8 channels Using 16 octaves of pink noise Channels count (8) not available for playbacks: Invalid argument Setting of hwparams failed: Invalid argument My neophyte instinct tells me that the problem is interoperability issue between the Radeon Audio controller and the SC-09TX receiver. That would be great to be able to tweak the hda driver to workaround the problem but if I was able to manually program the hda codec module to accept 8 channel LPCM input, that would be good enough for me. My understanding is that in the advent of HDMI handshake failure, the sound source fallbacks to the bare minimum requirement that the HDMI standard requires. I have started to read Intel HDA manual. What I would like to know is: Is it known if my particular HDA device is able to output 48KHz 8 channels LPCM? would it configurable manually? Which HDA verbs should get familiar with if I want to tweak the code to configure the controller manually?

[alsa-devel] 7.1 surround channels missing on CS46xx
by Ondrej Zary 16 May '13

16 May '13

Hello, I got a Hercules Fortissimo 7.1 sound card (CS4624 + two CS4294) but snd-cs46xx driver supports only 6 channels (front, rear, center/lfe). The surround output (7&8) is not supported - as seen in dsp_spos_scb_lib.c: case DSP_PCM_S71_CHANNEL: /* TODO */ snd_BUG(); break; Tried to add a code for this, mostly copying the center/lfe code but I miss some data: - which slots (ACOSV_SLVx) should be used (maybe 10 and 12?) - what are the channel_disp and fifo_addr values for cs46xx_dsp_create_codec_out_scb() function - what values should S71_MIXER_SCB_ADDR and S71_CODEC_SCB_ADDR be (maybe 0x1b0 and 0x1c0?) -- Ondrej Zary
