Hello everyone! I encountered an ALSA problem which I chose to share with the [Alsa-user] list 2 weeks ago, after having takled the problem a few months, but I still haven't got any answer whether it is a known bug/configuration problem or anything else. I am willing to provide any further information, but I would be really thankful if anyone could have a peek at the problem described below:
Thank you very much, Alex Marandon -----Message d'origine----- De : [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] la part de Alex Marandon Envoye : dimanche 4 janvier 2004 20:21 A : [EMAIL PROTECTED] Objet : [Alsa-user] intel8x0 - SPDIF output (not again!) Hello list! I am currently running Debian Sid on a Shuttle SB61G2 featuring a shuttle FB61 mainboard with intel 865G chipset (Northbridge) and intel ICH5 (southbridge). The audio chipset is a 5.1 channel AC97 2.2 compliant : Realtek ALC650. (see lspci output below) I "slipstreamed" alsa-drivers-1.0.0rc2 into the kernel 2.6.0 source (to circumvent the "CONFIG_HAVE_PDE already defined" during compilation problems, like it is explained in the wiki : http://alsa.opensrc.org/index.php?page=AlsaBuild2.6 for those who ask), and I compiled the intel8x0 as a module. I added to modules.conf the lines (see below), and I created the .asoundrc file in ~ (see below) Everything worked fine, I get sound through the jack output without any problems. I wanted to use the spdif output, and I checked for the device number in /proc/asound/pcm (see below) which was 4 (btw, it was 1 before in 0.9.7c, is this normal?). When I try : aplay -D hw:0,0 [file] - (jack output) the file actually plays ('Playing [file] Signed 16 bit Little Endian') and when I try : aplay -D hw0:4 [file] - (IEC958 spdif output) I get the ('Playing [file] Signed 16 bit Little Endian') output but without sound, and after 5-10 seconds I get the error: aplay:pcm_write:1083: write error: Input/output error I added various output below, but if you need any other file output, just ask, and I'll gladly add them to the list. Thank you for reading this mail, Alex Marandon ######## lspci -vv start ############# 00:1f.5 Multimedia audio controller: Intel Corp. 82801EB AC'97 Audio Controller (rev 02) Subsystem: Holco Enterprise Co, Ltd/Shuttle Computer: Unknown device c09d Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0 Interrupt: pin B routed to IRQ 12 Region 0: I/O ports at dc00 [size=256] Region 1: I/O ports at e000 [size=64] Region 2: Memory at f6081000 (32-bit, non-prefetchable) [size=512] Region 3: Memory at f6082000 (32-bit, non-prefetchable) [size=256] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=375mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME- ######## lspci -vv end ############# ######### modules.conf - start ########## #ALSA Portion alias char-major-116 snd alias snd-card-0 snd-intel8x0 #Module options should go here # OSS/Free Portion alias char-major-14 soundcore alias sound-slot-0 snd-card-0 # card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss ######### modules.conf - end ############ ######### .asoundrc - start ########## pcm.intel8x0 { type hw card 0 } ctl.intel8x0 { type hw card 0 } ######### .asoundrc - end ############ ######### /proc/asound/pcm - start ########### 00-00: Intel ICH : Intel ICH5 : playback 1 : capture 1 00-01: Intel ICH - MIC ADC : Intel ICH5 - MIC ADC : capture 1 00-02: Intel ICH - MIC2 ADC : Intel ICH5 - MIC2 ADC : capture 1 00-03: Intel ICH - ADC2 : Intel ICH5 - ADC2 : capture 1 00-04: Intel ICH - IEC958 : Intel ICH5 - IEC958 : playback 1 ######### /proc/asound/pcm - end ########### #### /proc/asound/card0/codec97#0/ac97#0-0 - start ###### 0-0/0: Realtek ALC650 rev 3 Capabilities : DAC resolution : 20-bit ADC resolution : 18-bit 3D enhancement : Realtek 3D Stereo Enhancement Current setup Mic gain : +0dB [+0dB] POP path : pre 3D Sim. stereo : off 3D enhancement : off Loudness : off Mono output : MIX Mic select : Mic1 ADC/DAC loopback : off Extended ID : codec=0 rev=1 LDAC SDAC CDAC DSA=0 SPDIF DRA VRA Extended status : LDAC SDAC CDAC SPDIF=res SPDIF VRA PCM front DAC : 48000Hz PCM Surr DAC : 48000Hz PCM LFE DAC : 48000Hz PCM ADC : 22050Hz SPDIF Control : Consumer PCM Category=0x2 Generation=1 Rate=44.1kHz SPDIF In Status : Not Locked #### /proc/asound/card0/codec97#0/ac97#0-0 - end ###### ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
