Project: ALSA - driver
Issue ID: 2159
Category: PCI - ymfpci
Reproducibility: always
Severity: minor
Priority: normal
Status: feedback
Distribution: Debian
Kernel Version: 2.6.15

Summary: ac3 passthrough not working on recent versions
Description:
Using the following AC3 passthrough with mplayer works:
Linux 2.4.31
alsa-driver 1.0.8-7 (debian stable packaged)

Using Linux 2.6.15 (both with alsa-driver 1.10rc3 that ships with the
kernel and
alsa-driver 1.0.11) it doesn't work. The reciever just says "unlock" and
stays quiet.

The only change is booting with different kernels, no other config or
hardware is touched, so this must be a driver regression.

The card is YMF-754 based, connected with coax spdif to my HK reciever.

If you need more info, just tell me and I'll dig it up.

Please post /etc/asound.state

Are you sure that all controls are created ?

YMFPCI_DOUBLE(SNDRV_CTL_NAME_IEC958("AC97 ", PLAYBACK,VOLUME), 0,
YDSXGR_ZVOUTVOL),
YMFPCI_DOUBLE(SNDRV_CTL_NAME_IEC958("", CAPTURE,VOLUME), 0,
YDSXGR_ZVLOOPVOL),
YMFPCI_DOUBLE(SNDRV_CTL_NAME_IEC958("AC97 ",PLAYBACK,VOLUME), 1,
YDSXGR_SPDIFOUTVOL),
YMFPCI_DOUBLE(SNDRV_CTL_NAME_IEC958("",CAPTURE,VOLUME), 1,
YDSXGR_SPDIFLOOPVOL),
YMFPCI_SINGLE(SNDRV_CTL_NAME_IEC958("",PLAYBACK,SWITCH), 0,
YDSXGR_SPDIFOUTCTRL, 0),
YMFPCI_SINGLE(SNDRV_CTL_NAME_IEC958("",CAPTURE,SWITCH), 0,
YDSXGR_SPDIFINCTRL, 0),
YMFPCI_SINGLE(SNDRV_CTL_NAME_IEC958("Loop",NONE,NONE), 0,
YDSXGR_SPDIFINCTRL, 4),

for (idx = 0; idx < ARRAY_SIZE(snd_ymfpci_controls); idx++) {
if ((err = snd_ctl_add(chip->card,
snd_ctl_new1(&snd_ymfpci_controls[idx], chip))) < 0)
return err;
}

Added /etc/asound.state from ALSA 1.0.12rc1. AC3 passthrough is not working
for me. To my eyes the controls seem to be present, and the digital output
does work, just not AC3 pass-through.
