I'm running Fedora 7 on a PS3 (2.6.22 kernel, 1.0.14rc2 alsa). I'm trying to create a multi-channel device by following the instructions at: http://www.alsa-project.org/alsa-doc/doc-php/asoundrc.php On the section on "virtual multi channel devices" I also tried changing the slave b hardware number to 7 to match my set-up. ( and tried putting 7 -> 0 and 1->0 to make the snd_ps3 the "second" device w/o record). attempting to run the test command yeilds: [root@ps3 Surround-SDL-testfiles]# arecord -f S16_LE -r 44100 -c 4 -D multi | aplay -f S16_LE -r 44100 -c 4 -D multi arecord: main:545: audio open error: No such file or directory aplay: playback:2018: read error to remove the record part of things, I've also tried : [root@ps3 Surround-SDL-testfiles]# aplay -f S16_LE -r 44100 -c 4 -D multi dolby-canyon.ogg Playing raw data 'dolby-canyon.ogg' : Signed 16 bit Little Endian, Rate 44100 Hz, Channels 4 aplay: set_params:878: Broken configuration for this PCM: no configurations available (I also tried Big-endian). Looking at http://bugtrack.alsa-project.org/main/index.php/Matrix:Module-usb-audio the relevent part of my kernel config file is below: and the output of lsmod. I notice that soundcore.o is in my build tree, but I'm unable to find a soundcore.ko file. I'm assuming that this is being statically linked into the kernel. (I can find .soundcore_open in the System.map file for my kernel). this looks reasonable to me. From my various tries at this I believe I have a configuration issue, and would appriciate some pointers in the right direction. thanks GT ***********Config info: ****************** I'm able to run speaker-test -c 2 and get sound out of L&R for each of the two cards. the output of aplay -l is [root@ps3 Surround-SDL-testfiles]# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PS3 [PS3], device 0: SPDIF [SPDIF] Subdevices: 1/1 Subdevice #0: subdevice #0 card 7: MP3 [Sound Blaster MP3+], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 The out-put of aplay -l is as follows: [root@ps3 Surround-SDL-testfiles]# aplay -L null Discard all samples (playback) or generate zero samples (capture) default:CARD=MP3 Sound Blaster MP3+, USB Audio Default Audio Device front:CARD=MP3,DEV=0 Sound Blaster MP3+, USB Audio Front speakers surround40:CARD=MP3,DEV=0 Sound Blaster MP3+, USB Audio 4.0 Surround output to Front and Rear speakers surround41:CARD=MP3,DEV=0 Sound Blaster MP3+, USB Audio 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=MP3,DEV=0 Sound Blaster MP3+, USB Audio 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=MP3,DEV=0 Sound Blaster MP3+, USB Audio 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=MP3,DEV=0 Sound Blaster MP3+, USB Audio 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers iec958:CARD=MP3,DEV=0 Sound Blaster MP3+, USB Audio IEC958 (S/PDIF) Digital Audio Output >From http://bugtrack.alsa-project.org/main/index.php/Matrix:Vendor-Creative_Labs I see that only analog output is supported .configure file: # # Sound # CONFIG_SOUND=y # # Advanced Linux Sound Architecture # CONFIG_SND=m CONFIG_SND_TIMER=m CONFIG_SND_PCM=m CONFIG_SND_HWDEP=m CONFIG_SND_RAWMIDI=m CONFIG_SND_SEQUENCER=m # CONFIG_SND_SEQ_DUMMY is not set # CONFIG_SND_MIXER_OSS is not set # CONFIG_SND_PCM_OSS is not set # CONFIG_SND_SEQUENCER_OSS is not set # CONFIG_SND_DYNAMIC_MINORS is not set CONFIG_SND_SUPPORT_OLD_API=y CONFIG_SND_VERBOSE_PROCFS=y # CONFIG_SND_VERBOSE_PRINTK is not set # CONFIG_SND_DEBUG is not set # # Generic devices # # CONFIG_SND_DUMMY is not set # CONFIG_SND_VIRMIDI is not set # CONFIG_SND_MTPAV is not set # CONFIG_SND_SERIAL_U16550 is not set # CONFIG_SND_MPU401 is not set # # ALSA PowerMac devices # # # ALSA PowerMac requires I2C # # # ALSA PowerPC devices ***** loaded modules **** [root@ps3 usb]# lsmod Module Size Used by hidp 27896 0 rfcomm 59208 0 l2cap 34312 6 hidp,rfcomm snd_usb_audio 114200 0 snd_usb_lib 25544 1 snd_usb_audio snd_rawmidi 34408 1 snd_usb_lib snd_ps3 19128 0 hci_usb 23172 2 bluetooth 81524 8 hidp,rfcomm,l2cap,hci_usb usb_storage 54236 0 snd_seq_device 11692 1 snd_rawmidi snd_hwdep 14368 1 snd_usb_audio snd_pcm 123132 2 snd_usb_audio,snd_ps3 usbhid 28828 0 snd_page_alloc 10816 1 snd_pcm sys_manager 7052 0 [permanent] snd_timer 33872 1 snd_pcm snd 77328 7 snd_usb_audio,snd_rawmidi,snd_ps3,snd_seq_device,snd_hwdep,snd_pcm,snd_timer sg 46816 0 ext2 75584 5 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
