I'm messing around with that problem for a while
and I guess some help is needed here :( Running a stock but uptodate ubuntu 5.10 (kernel Linux version 2.6.12-10-686 ([EMAIL PROTECTED]) (gcc version 3.4.5 20050809 (prerelease) (Ubuntu 3.4.4-6ubuntu8.1)) with alsa 1.0.9a on a Shuttle Zen ST62K (ati ixp chipset) My goal is to connect the shuttle to an HT amp using the optical spdif and make a lot of noise with aplay mplayer and the like o:) What works: alsamixer says 00 for the iec958 device (not MM) lsmod ... atiixp 6032 1 snd_atiixp 20288 0 snd_ac97_codec 83932 1 snd_atiixp snd_pcm_oss 52704 0 snd_mixer_oss 19296 1 snd_pcm_oss snd_pcm 88840 3 snd_atiixp,snd_ac97_codec,snd_pcm_oss snd_timer 24164 1 snd_pcm snd 54884 6 snd_atiixp,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore 9600 1 snd snd_page_alloc 10600 2 snd_atiixp,snd_pcm pci_hotplug 27508 0 ... aplay -l **** List of PLAYBACK Hardware Devices **** card 0: IXP [ATI IXP], device 0: ATI IXP AC97 [ATI IXP AC97] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: IXP [ATI IXP], device 1: ATI IXP IEC958 [ATI IXP IEC958 (AC97)] Subdevices: 1/1 Subdevice #0: subdevice #0 What does not work: mplayer -ao alsa:device=hw=0.1 noise.mp3 (tried various things here... spdif iec958 ...) or aplay -D ... And there is no signal on the optical output. (blank amp and no visible led activity on the toslink output) I've skimmed quite a lot of google/FAQ/HOWTO and the atiixp.c from the alsa driver source but no luck so far. So... I'm probably missing something obvious here. But what? Thank you for your help. |
