Today I have the same audio lagging problem again. The symptom is similar (audio output hanging for a very short (but noticeable) time), although it is less frequent (about one lagging per 90 seconds). At the same time I got a lot of error messages from wireless network again in the /var/log/syslog file. Here is the content of that file within the last 15 minutes: Sep 8 19:51:06 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 19:51:54 dbl-pc kernel: [25503.624905] ath5k phy0: noise floor calibration timeout (2412MHz) Sep 8 19:52:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 19:53:06 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 19:54:06 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 19:55:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 19:55:27 dbl-pc kernel: [25719.605410] ath5k phy0: noise floor calibration timeout (2412MHz) Sep 8 19:56:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 19:57:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 19:57:52 dbl-pc kernel: [25866.669275] ath5k phy0: noise floor calibration timeout (2412MHz) Sep 8 19:58:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 19:59:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 20:00:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 20:00:53 dbl-pc kernel: [26050.488420] ath5k phy0: noise floor calibration timeout (2412MHz) Sep 8 20:01:06 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 20:02:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 20:03:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS Sep 8 20:04:07 dbl-pc wpa_supplicant[3165]: CTRL-EVENT-SCAN-RESULTS So I really suspect that the audio lagging and the wireless error messages are somehow connected.
