Troubles with ALSA Sound Card drivers for ES1868 / ES1688

Troubles with ALSA Sound Card drivers for ES1868 / ES1688

Post by Andrea Fernando Liberat » Fri, 23 Oct 1998 04:00:00

I use a slackware distribution with kernel upgraded to 2.0.34
My pc is equipped with an "anonymous" ESS 1868 Sound Card.

The original kernel drivers OSS/Lite identifies it as a ESS 1688, baut
it works good.

Trying to work with multitrack-2.2 with full-duplex, i've compiled &
installed ALSA drivers 0.2.0-pre8

These drivers seems to work (i can able to load the modules, i can cat
from and to /dev/dsp hearing the sounds) but  all the sound oriented
that previously worked doesn't work anymore.

multitrack says "No soundcards available.  Record and playback
wavplay says "Invalid argument: Audio block size (1024 bytes)".

Can i do something to fix this? Or i have to go back to OSS/Lite and
forget the full-duplex? Or buy a OSS/Linux?

The /etc/modules.conf configuration i'm using is the following (i didn't
find enough documentation about the way to make this configuration,
i've just argued how to make it ):

extract from /etc/modules.conf

alias char-major-14 snd
alias snd-minor-oss-0 snd-audiodrive1688
alias snd-minor-oss-3 snd-pcm1-oss
alias snd-minor-oss-4 snd-pcm1-oss
alias snd-minor-oss-5 snd-pcm1-oss
alias snd-minor-oss-12 snd-pcm1-oss
alias snd-card-0 snd-audiodrive1688
options snd snd_major=14 snd_cards_limit=1
options snd-audiodrive1688 snd_index=1 snd_port=0x220 snd_irq=9
snd_dma8=1 snd_dma8_size=64



1. Sound Card Help: ALSA driver, ESSOLO 1938 PCI Sound Card

I actually got pretty far into this, but can't make a peep come out of the
speakers (I just had a horrible thought - speakers are plugged in and turned

Got ALSA Drivers, utilities, and library files, did standard configure, make,
make install for each.
In a console window under KDE, did the following:
1. insmod soundcore - got nothing back, so I assume that worked.
2. ran the snddevices script - it happily reported making a ton of devices.
3. Edited my etc/modules.conf to the following

alias net-pf-4 off
alias net-pf-5 off
alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-card-es1938
alias sound-slot-0 snd-card-0

4. ran modprobe snd-card-es1938 - got nothing back, so I assume that worked as

5. I tried a couple of the tools available under the "multimedia" option of the
KDE menu - none of them can access the output dev. I tried the chmod, still no
joy. When I run /utils/alsasound start, it reports that the driver is already
running. I postulate that may be so, but would like to confirm my hypothesis by
actually hearing something from the speakers. Any help would be appreciated.
