[Alsa-user] Can't get spdif working with ALSA and FC6 on ECS L4S5MG/651+ motherboard

Hi, I have tried just about everything that I can think of in order to get the SPDIF port on my motherboard to work. I am putting together a MythTV box and so I would like digital audio with AC3 passthrough to work for surround sound from DVD's and HDTV content. The spdif output works fine under Windows (I have a dual boot setup), and so I am highly confident that the hardware is working. I currently have the spdif output hooked into the spdif coax input of a Sony Dream System. The analog sound is working fine under linux, and so I believe that the sound card is being detected properly. The audio device on my motherboard is a SiS7012 chipset which is supposed to be supported by the intel8x0 ALSA driver, and as far as I can tell it is configured correctly in the kernel and modprobe.conf, but I am not an expert in drivers and kernel level stuff so I don't know. The thing that is most puzzling to me is that when I run aslamixer, I don't see an IEC958 device or a spdif device. This makes me wonder if for some reason the ALSA driver doesn't recognize the spdif port on the motherboard (BTW the motherboard just has a spdif header on it and I built a backplate for the case with a spdif coax plug on it.) When I first loaded Windows it didn't recognize the spdif port either. I had to get a more up to date driver from SiS before I could get the spdif port working. I have included as much information as I can think of below in hopes that someone here can figure out what I am missing. Thanks, Rob Here is a list of some of the things that I have tried: I tried running alsaconf as suggested on several sites, but as far as I can tell it is not installed on my system (can't find it with a locate alsaconf), and it is not included in any of the FC6 rpms (including alsa-utils). I guess I could compile ALSA from scratch, but I don't want to go to the trouble unless there aren't any other good options left. I have tried to follow all of the advice on the following web pages: http://alsa.opensrc.org/DigitalOut http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound_with_AC3_and_SPDIF And when I try to run "aplay -D" I get the following errors: # aplay -D spdif /usr/share/sounds/KDE_Startup.wav aplay: main:550: audio open error: Device or resource busy # aplay -D hw:0,0 /usr/share/sounds/KDE_Startup.wav aplay: main:550: audio open error: Device or resource busy # aplay -D hw:spdif /usr/share/sounds/KDE_Startup.wav ALSA lib pcm_hw.c:1357:(_snd_pcm_hw_open) Invalid value for card aplay: main:550: audio open error: No such device # aplay -D plug:spdif /usr/share/sounds/KDE_Startup.wav aplay: main:550: audio open error: Device or resource busy # aplay -D ALSA:spdif /usr/share/sounds/KDE_Startup.wav ALSA lib pcm.c:2143:(snd_pcm_open_noupdate) Unknown PCM ALSA:spdif aplay: main:550: audio open error: No such file or directory If I don't use the -D (or I use default) everything works as it should (except I only get stereo output from the line out/headphone jack): # aplay -D default /usr/share/sounds/KDE_Startup.wav Playing WAVE '/usr/share/sounds/KDE_Startup.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono # aplay /usr/share/sounds/KDE_Startup.wav Playing WAVE '/usr/share/sounds/KDE_Startup.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono If I use the ~/.asoundrc from http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound, I get the following error: $ aplay -D default /usr/share/sounds/KDE_Startup.wav ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave aplay: main:550: audio open error: Permission denied And if I use the /etc/asound.conf from http://www.mythtv.org/wiki/index.php/Configuring_Digital_Sound_with_AC3_and_SPDIFI get this error: # aplay /usr/share/sounds/KDE_Startup.wav aplay: main:550: audio open error: Device or resource busy Here is the result of aplay -l and aplay -L: # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: SI7012 [SiS SI7012], device 0: Intel ICH [SiS SI7012] Subdevices: 0/1 Subdevice #0: subdevice #0 # aplay -L PCM list: hw { @args.0 CARD @args.1 DEV @args.2 SUBDEV @args.CARD { type string default { @func getenv vars { 0 ALSA_PCM_CARD 1 ALSA_CARD } default { @func refer name 'defaults.pcm.card' } } } @args.DEV { type integer default { @func igetenv vars { 0 ALSA_PCM_DEVICE } default { @func refer name 'defaults.pcm.device' } } } @args.SUBDEV { type integer default { @func refer name 'defaults.pcm.subdevice' } } type hw card $CARD device $DEV subdevice $SUBDEV } plughw { @args.0 CARD @args.1 DEV @args.2 SUBDEV @args.CARD { type string default { @func getenv vars { 0 ALSA_PCM_CARD 1 ALSA_CARD } default { @func refer name 'defaults.pcm.card' } } } @args.DEV { type integer default { @func igetenv vars { 0 ALSA_PCM_DEVICE } default { @func refer name 'defaults.pcm.device' } } } @args.SUBDEV { type integer default { @func refer name 'defaults.pcm.subdevice' } } type plug slave.pcm { type hw card $CARD device $DEV subdevice $SUBDEV } } plug { @args.0 SLAVE @args.SLAVE { type string } type plug slave.pcm $SLAVE } shm { @args.0 SOCKET @args.1 PCM @args.SOCKET { type string } @args.PCM { type string } type shm server $SOCKET pcm $PCM } tee { @args.0 SLAVE @args.1 FILE @args.2 FORMAT @args.SLAVE { type string } @args.FILE { type string } @args.FORMAT { type string default raw } type file slave.pcm $SLAVE file $FILE format $FORMAT } file { @args.0 FILE @args.1 FORMAT @args.FILE { type string } @args.FORMAT { type string default raw } type file slave.pcm null file $FILE format $FORMAT } null { type null } cards 'cards.pcm' front 'cards.pcm.front' rear 'cards.pcm.rear' center_lfe 'cards.pcm.center_lfe' side 'cards.pcm.side' surround40 'cards.pcm.surround40' surround41 'cards.pcm.surround41' surround50 'cards.pcm.surround50' surround51 'cards.pcm.surround51' surround71 'cards.pcm.surround71' iec958 'cards.pcm.iec958' spdif 'cards.pcm.iec958' modem 'cards.pcm.modem' phoneline 'cards.pcm.phoneline' default 'cards.pcm.default' dmix 'cards.pcm.dmix' dsnoop 'cards.pcm.dsnoop' And finally here is the output from the aadebug.sh script from the ALSA wiki: ALSA Audio Debug v0.1.0 -
