Laptops :: Panasonic CF-25 Runs awesome no sound! Any Ideas?



Yes..it has a magnesium alloy case...the keyboard is waterproof!, and it has a built in carry handle!

Our CF-25 they used where I work to test telephone ckts...could drop from a telephone pole and not break it!

You could litteraly smack someone upside the head with it and not damage this laptop!

The old ones were built for strength not speed...the newer ones  Panasonic Toughbooks are tough as nails, and pretty dang fast!!!!

Keep looking around...im sure all you have to do is tell it to manually activate the sound module and what io and irq to use (I had to do this with my Compaq LTE 5300)

Im having the same problem with my CF-71. From what Ive found, it has a different chip (yahama-something). Anyone have an idea?

The Sound Setup

The Yamaha YMF744 runs with OSS/Lite and standard SoundblasterPro settings. I have not tried ALSA which should support this chipset directly.

You can look up the actual compatibility settings for memory addresses and interrupts for your machine in the BIOS.

Update: The 256AV is a combined Video/Sound chip. Linux Kernels since 2.2.14 contain a native sound driver for it. See Documentation/sound/NM256.txt for details how to install it, and to learn about the strange use of video memory of this chipset.
Having learned this recently, i'm in doubt, that the sound chip is really a YMF744. Maybe the 256AV is doing it all alone. Unfortunately i can't test this, because i do not own the CF-71 any more. If anybody can confirm the YMF744 or the NM256, please drop me a mail.

Actually Marcelino Mata did:

...the Panasonic CF-71 has a YMF-715E sound chip. I read this information off the chip located under the hard drive.
I have not had much luck with Alsa yet but it works fine with OSS with NeoMagic 256AV,YMF 715 and OPL3-SAx (YMF719). With the Neomagic driver, OSS selects the OPL3-SAx driver. It got it working with a 2.6 based distro at this point.

Hi Windancer

I'm working on the same problem. I'm no guru, but I had a spark of hope last night. I booted DSL 2.0 in DSL alsa mode,logged in as user DSL and loaded gnu_utils.dsl and the dsl_dpkg.dsl. Then ran Alsa setup from the menu.( I down loaded the alsa.dsl from the test section.) The setup program detected the sound card as a legacy isa card and used the sb8 driver. I guess I should mention that I have these BIOS settings( io=220, wss=530, irq=5, dma=1). After the setup program finished it's thing I ran XMMS and it worked, till I rebooted. So that's where I'm at. I ran out of time to try anything further. I'll try again tonight.

add this to your /opt/bootlocal.sh

# Activate Soundcard
modprobe sb io=220 wss=530 irq=5 dma=1

You can edit this to the settings of your system

Was that sb8 or what?!?!
