Hi, Hi,
I was hoping I could get some help troubleshooting some audio quality issues I am running into. Specifically, I am getting a lot of *pops/crackles* when I play audio files. It shows up when I move from 2-channel to 4/5 channel audio (via pauvcontrol) - I am using a USB X-FI sound-card with the Meego IVI. I have tried changing the resample method (going from ffmpeg to high-quality) and setting tsched=0, neither making any noticeable difference. The only things I saw in /var/log/messages that seemed relevant was: messages:Aug 6 16:59:26 localhost pulseaudio[570]: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! messages:Aug 6 16:59:26 localhost pulseaudio[570]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_usb_audio'. Please report this issue to the ALSA developers. messages:Aug 6 16:59:26 localhost pulseaudio[570]: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. And this was spout out of dmesg [ 21.857184] ALSA sound/usb/mixer.c:2110: status interrupt: c0 00 [ 21.897058] ALSA sound/usb/mixer.c:2110: status interrupt: c0 00 [ 21.961062] ALSA sound/usb/mixer.c:2110: status interrupt: c0 00 I have already eliminated the speakers and the amp (played music from a different source and they sounded fine). Let me know what else I should post (I could record the sound, if that would be useful). Thanks in advance, Nasa ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.
