Some error messages can be reproduced by set default-sample-format to s24le But cannot reproduce SNDRV_PCM_IOCTL_HW_PARAMS Any error meesage in system log , it seem snd_usb_pcm_hw_params return error with your usb sound card > >> >> ( 0.091| 0.000) D: [pulseaudio] alsa-util.c: Trying hw:1,1,0 with SND_PCM_NO_AUTO_FORMAT ... >> ( 0.091| 0.000) D: [pulseaudio] alsa-util.c: Managed to open hw:1,1,0 >> ( 0.091| 0.000) I: [pulseaudio] alsa-util.c: Disabling tsched mode since BATCH flag is set >> ( 0.091| 0.000) D: [pulseaudio] alsa-util.c: Maximum hw buffer size is 3640 ms >> ( 0.091| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.091| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.092| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.092| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.092| 0.000) D: [pulseaudio] alsa-util.c: Set neither period nor buffer size. >> ( 0.093| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.093| 0.000) I: [pulseaudio] alsa-util.c: snd_pcm_hw_params failed: Input/output error >> ( 0.093| 0.000) D: [pulseaudio] alsa-util.c: Trying hw:1,1,0 without SND_PCM_NO_AUTO_FORMAT ... >> ( 0.093| 0.000) D: [pulseaudio] alsa-util.c: Managed to open hw:1,1,0 >> ( 0.093| 0.000) I: [pulseaudio] alsa-util.c: Disabling tsched mode since BATCH flag is set >> ( 0.093| 0.000) D: [pulseaudio] alsa-util.c: Maximum hw buffer size is 3640 ms >> ( 0.093| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.094| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.094| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.094| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.094| 0.000) D: [pulseaudio] alsa-util.c: Set neither period nor buffer size. >> ( 0.095| 0.000) I: [pulseaudio] (alsa-lib)pcm_hw.c: SNDRV_PCM_IOCTL_HW_PARAMS failed (-5) >> ( 0.095| 0.000) I: [pulseaudio] alsa-util.c: snd_pcm_hw_params failed: Input/output error >> ( 0.095| 0.000) D: [pulseaudio] alsa-util.c: Trying plug:hw:1,1,0 with SND_PCM_NO_AUTO_FORMAT ... >> >> Do capture work as there is no output of snd_pcm_dump of the snd-usb-audio 's hw params ? >> > Well, after system restart Mic is not working, while it is available and selected in UI. > After single switch to Line and back to Mic it starts working fine. > I wasn't able to reproduce it twice during working session, so, here is verbose log of the first start right after system restart where Mic was initially selected but didn't work, and started working after switching to Line and back: http://pastebin.com/fr0cTUu3 It is strange that hardware volume are -19.5dB/-20dB when dB range of Mic capture volume and Line Capture Volume from -12 dB to +12dB 9.416| 0.000) D: [alsa-source-USB Audio] alsa-mixer.c: Setting analog-input-linein (analog-input-linein) priority=0 ( 9.418| 0.001) I: [alsa-source-USB Audio] alsa-source.c: Successfully enabled deferred volume.
