[Alsa-user] Failed to work Yamaha snd-card-opl3sa2 module , On my Tecra 8000 Laptop

[Newmail]

Somebody can tell me why on my Laptop Tecra 8000, i can`t configure Yamaha oplsa2/3 card using Alsa driver....   Alsa driver was compiled with: ./configure --with-isapnp=yes --with-sequencer --with-debug-full.   Also, i want to mention that on my laptop not exist /proc/isapnp, also no cards founded if i use pnpdump so in conclusion, no /etc/isapnp.conf file...   Also in BIOS i found this settings:   WSS I/O ADD 0x530 SBPRO I/O ADD 0x220 Synthesyzer I/O ADD 0x388 WSS & SB PRO & MPU401 IRQ Level = IRQ5 WSS Play DMA = Channel 1 WSS Rec & SB Pro DMA = Channel 0 Control I/O Address = 538H MPU401(MIDI I/F) = 0x330   I use kernel 2.4.16 on RedHat 7.2 . See below my /etc/modules.conf. For conformity you will se 3 sections, for my souncard, each of this sections using a different driver.   #Activare portul paralel alias parport_lowlevel parport_pc #End Activare portul paralel   #Activare USB bus alias usb-controller usb-uhci #End Activare USB bus   #Activare WebCam Philips 750k alias char-major-81-0 pwc post-install pwc /sbin/insmod --force /lib/modules/2.4.16/kernel/drivers/usb/pwcx-i386.o >/dev/null 2>&1  || : alias dsp1 audio alias mixer1 audio #End Activare WebCam Philips 750k   #Yamaha sound card using (Windows Sound System kernel driver) #alias sound-slot-0 ad1848 #options ad1848 io=0x530 irq=5 dma=1 dma2=0 #post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || : #pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || : #options sound dmabuf=1 #alias synth0 opl3 #options opl3 io=0x388 #End Yamaha sound card using (Windows Sound System kernel driver)     #Yamaha sound card using (Yamaha-oplsa2/3 kernel driver) #alias sound-slot-0 opl3sa2 #options opl3sa2 mss_io=0x530 irq=5 dma=1 dma2=0 mpu_io=0x330 io=0x538 #post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || : #pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || : #options sound dmabuf=1 #alias midi opl3 #options opl3 io=0x388 #End Yamaha sound card using (Yamaha-oplsa2/3 kernel driver)     #AND HERE IS THE PROBLEM #Yamaha sound card using Alsa-driver OPLSA2/3   #Alsa alias char-major-116 snd options snd snd_major=116 snd_cards_limit=1 snd_device_mode=0666 snd_device_uid=0   alias snd-card-0 snd-card-opl3sa2 options snd-card-opl3sa2 snd_index=0 snd_id="Yamaha" \  snd_port=0x538 snd_sb_port=0x220 snd_wss_port=0x530 \  snd_midi_port=0x330 snd_fm_port=0x388 snd_irq=5 \  snd_dma1=1 snd_dma2=0 snd_opl3sa3_ymode=2 #End Alsa   #OSS support alias char-major-14 soundcore alias sound-slot-0 snd-card-0 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 #End OSS support   #End Yamaha sound card using Alsa-driver OPLSA2/3   All the time i received error message : Invalid IO or irq parametters.......... I suspect that snd_port=0x538 is bad, but i`m not sure.........   Has anybody and idea what is wrong   Thanks in advance for your help,   Alexandru S.   PS: A retoric question: Why the documenbtation founded in Alsa driver source code is worst...........? Almost ALL EXAMPLES are depricated AND INCOMPLETED!!!!????? Never in my life i can read a worse documentation then this.....:-)
