Hi, suggestion given on the list does not help. Still no sound. Playvawe output is: ALSA lib pcm_hw.c:521:(snd_pcm_hw_prepare) SNDRV_PCM_IOCTL_PREPARE failed: Device or resource busy ALSA lib pcm_hw.c:521:(snd_pcm_hw_prepare) SNDRV_PCM_IOCTL_PREPARE failed: Device or resource busy ALSA lib pcm_hw.c:521:(snd_pcm_hw_prepare) SNDRV_PCM_IOCTL_PREPARE failed: Device or resource busy Look at strace output at bug # 136082. There are several select(.....) timeouts related to previous ioctl. Some device is unavailable but which and why? I don't understand more. Somebody can fix it? Darek Borkowski
