Hi, i have problems to set up a soundcard in a xen guest. Actually i tried the same in another xen guest system, with different hardware, so i thinks it''s not the hardware. I assigned the pci soundcard to the guest with the xen kernel cmdline: root=/dev/mapper/ru-root ro console=tty0 xencons=tty pciback.hide=(00:0d.0) the guest is taking the card with pci = [ ''00:0d.0'' ] ru:~# lspci 00:00.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10) Everything looks fine, but when i use aplay i.e. : ru:~# aplay ALSA lib pcm_direct.c:985:(snd_pcm_direct_initialize_slave) unable to install hw params ALSA lib pcm_dmix.c:876:(snd_pcm_dmix_open) unable to initialize slave aplay: main:550: audio open error: Cannot allocate memory Here are some additional infos: Host: Xen 3.1.0 Linux ... 2.6.18-4-xen-686 #1 SMP Thu May 10 03:24:35 UTC 2007 i686 GNU/Linux Guest: snd_cmipci 32384 0 gameport 15592 1 snd_cmipci snd_pcm 69764 1 snd_cmipci snd_page_alloc 10472 1 snd_pcm snd_opl3_lib 10688 1 snd_cmipci snd_timer 21924 2 snd_pcm,snd_opl3_lib snd_hwdep 9604 1 snd_opl3_lib snd_mpu401_uart 8864 1 snd_cmipci snd_rawmidi 23456 1 snd_mpu401_uart snd_seq_device 8588 2 snd_opl3_lib,snd_rawmidi snd 47876 8 snd_cmipci,snd_pcm,snd_opl3_lib,snd_timer,snd_hwdep,snd_mpu401_uart,snd_rawmidi,snd_seq_device soundcore 10016 1 snd ipv6 229088 10 8250 28164 0 serial_core 20288 1 8250 ext3 120072 1 jbd 53224 1 ext3 mbcache 9124 1 ext3 dm_crypt 11656 0 dm_mirror 20048 0 dm_snapshot 16320 0 dm_mod 51000 3 dm_crypt,dm_mirror,dm_snapshot processor 29608 0 Hope someone can help.
