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?)
