Narrative:

Departed runway 12 at lgb with a clearance to climb runway heading to maintain 3000 ft. The radar vector was a right turn directly into a group of aircraft. The map scale was at 10 mi and filled with targets. The first indication was a TA followed by an RA, descend, descend, descend. Shortly thereafter, climb, climb, climb, then monitor vertical speed. I remain convinced that following the RA was the safest action. I spoke with a coast approach supervisor and he informed me that the controller ordered a turn which we never received due to TCASII volume being too loud.

Original NASA ASRS Text

Title: ACR ON INITIAL CLB HAS TCASII RA TO DSND THEN TO CLB. RESPONDS.

Narrative: DEPARTED RWY 12 AT LGB WITH A CLRNC TO CLB RWY HDG TO MAINTAIN 3000 FT. THE RADAR VECTOR WAS A R TURN DIRECTLY INTO A GROUP OF ACFT. THE MAP SCALE WAS AT 10 MI AND FILLED WITH TARGETS. THE FIRST INDICATION WAS A TA FOLLOWED BY AN RA, DSND, DSND, DSND. SHORTLY THEREAFTER, CLB, CLB, CLB, THEN MONITOR VERT SPD. I REMAIN CONVINCED THAT FOLLOWING THE RA WAS THE SAFEST ACTION. I SPOKE WITH A COAST APCH SUPVR AND HE INFORMED ME THAT THE CTLR ORDERED A TURN WHICH WE NEVER RECEIVED DUE TO TCASII VOLUME BEING TOO LOUD.
