Subject: Bug#469061: twinkle: alsa audio troubles: ALSA lib
pcm_dmix.c:866:(snd_pcm_dmix_open) unable to open slave
Date: Monday 03 March 2008
From: Jens Thiele <[EMAIL PROTECTED]>
To: Debian Bug Tracking System <[EMAIL PROTECTED]>
Package: twinkle
Version: 1:1.1-2+b2
Severity: normal
I have some problems gettings conferencing to work.
Accepting a first call works. If I accept the second incoming call twinkle
hangs.
In the twinkle log file (~/.twinkle/twinkle.log) I get:
+++ 2-3-2008 14:57:32.032258 CRITICAL NORMAL t_alsa_io::open
snd_pcm_open failed: Das Gerät oder die Ressource ist belegt
(maybe I should have used LC_ALL=C - it means resource is busy)
On stdout(or stderr) I get:
ALSA lib pcm_dmix.c:866:(snd_pcm_dmix_open) unable to open slave

Playing with .asoundrc doesn't help.
I can run multiple instances of:
{ arecord | aplay; } &
just fine.

Subject: testing with twinkle 1.2: it seems it is caused by the ring script
Date: Mon, 07 Apr 2008 21:28:11 +0200
Package: twinkle
Version: 1:1.2-1
Followup-For: Bug #469061
after updating to 1.2-1 I tested again. This time I found out that my problem
is caused by using a ring script. (script_incoming_call=)
The strange thing is that using a minimal script like:
,----
| #!/bin/bash
| echo end
| exit 0
`----
it works. (The only minor issue is that there is no audible signal for the
incoming second call - but this probably is a separate wishlist bug)
Using a script like:
,----
| #!/bin/bash
| echo end
| for i in $(seq 0 2); do
| sleep 3
| done </dev/null >/dev/null 2>&1 &
| disown %1
| exit 0
`----
i get the error message again:
,----
| ALSA lib pcm_dsnoop.c:574:(snd_pcm_dsnoop_open) unable to open slave
| ALSA lib pcm_dsnoop.c:574:(snd_pcm_dsnoop_open) unable to open slave
| ALSA lib pcm_dsnoop.c:574:(snd_pcm_dsnoop_open) unable to open slave
