Subject: middle-layer errors when initializing pcm
Date: Mon, 31 Mar 2003 22:05:10 +0200 [thread overview]
Message-ID: <3E889F76.7050405@yahoo.es> (raw)
(maybe changing the subject someone answers ;) )
Hi:
I downloaded and compiled (it worked only with gcc-2.95 due to compiler
symbols on C++ object files) last non-official-release version from
Giuliano Pochini's site:
http://space.virgilio.it/g_pochini@virgilio.it/ea.html
The module loads with difficulties (it took about 1 min, I had to unload
the video card kernel module and the cards emits a continuous weird beep
which doesnt dissapear until I reboot my PC).
When trying to play something with aplay, I get:
pcm_open <----- from echoaudio.c pcmout_open()
ALSA ../alsa-kernel/core/pcm_native.c:1659: BUG? (err >= 0) (called from
d0c4f74a)
ALSA echoaudio.c:254: bad MAGIC (0xffffffff)
ALSA echoaudio.c:254: bad MAGIC (0xffffffff)
ALSA lib pcm-hw.c: 1078: (snd-pcm-hw-open) open /dev/snd/pcmC0D0p
failed: Invalid argument
aplay: main: 480: audio open error: Invalid argument
I have no experience programming kernel modules, but I know some C, can
anyone help me finding whats going on?
Alfonso Acosta
PS: Im using debian sid package alsa-source (alsa-driver 0.91) compiled
with detect debug level on a PC with a Darla24 sound card.
